FAQ

  • Q Why are planetary gears better?

    A Planetary gear systems are able to produce a lot of torque because the load is shared among multiple planet gears. This arrangement also creates more contact surfaces and a larger contact area between the gears than a traditional parallel axis gear system.

  • Q What is the role of planetary gear?

    A Planetary gears -function and construction. The task of gears is to transmit torques and to change the speed of rotation or the torque between the input and the output. When it is necessary to increase torque, planetary gears are often employed, particularly in the automobile industry.

  • Q How do planetary gears reduce speed?

    A A planetary gearhead takes a high-speed, low-torque input, say from an electric motor, then increases torque and reduces speed at the output by the gearhead ratio. This lets motors run at higher, more-efficient rpms in equipment that operates at low speeds.

  • Q What Are Planetary Gear Reducers?

    A Planetary gear reducers are compact components that strive to maximize the transmission of torque in various applications. The mechanisms ensure the transmission of high torque levels while simultaneously decreasing the required number of motor revolutions for a set level of power.

  • Q How do I choose a spindle motor?

    A
    Choose a CNC spindle that has the RPM, power, and cooling you need for your material. For Wood and Aluminum, a spindle with 24,000 RPM and 1kW power is good.For Steel, RPM between 15,000-18000 and power of 5.6 kW is good for up to 12mm tool size.
    Choosing a spindle motor depends on several factors such as the application, the material being machined, the required cutting speed, and the power and torque needed for the operation.  Here are some factors to consider when choosing a spindle motor:
    Power and torque: Consider the power and torque requirements for your application, as well as the materials being machined.  A more powerful motor will be needed for harder materials or larger workpieces.
    Speed: Choose a motor with a speed range that matches your application needs.  A higher speed will allow for faster cutting, while a lower speed may be needed for precision work.
    Cooling: Consider the cooling requirements for your application.  Some spindle motors may require external cooling systems, while others may have built-in cooling mechanisms.
    Accuracy: Choose a motor with the required accuracy and precision for your application.Some applications may require high accuracy and repeatability, while others may have looser tolerances.
    Noise and vibration: Consider the noise and vibration levels of the motor, as well as any dampening or vibration-absorbing measures that may be needed.
    Compatibility: Make sure the spindle motor is compatible with your machine and tooling.Check for any mounting or interface requirements.
    Cost: Consider the cost of the spindle motor and any additional equipment or accessories needed.
    Overall, it is important to carefully evaluate your application requirements and consult with a knowledgeable spindle motor supplier or spindle motor manufacturer.

  • Q What is a spindle in manufacturing?

    A
    A spindle is a rotating shaft with a fixture for holding a tool (in the case of a milling, grinding, or drilling spindle) or a workpiece (in the case of a turning spindle).    The spindle shaft serves as a support, a positioner, and a rotary drive for the tool or workpiece.
    In manufacturing, a spindle refers to a rotating component that is used to hold and rotate a tool or workpiece during machining or cutting operations.   Spindles are commonly found in machine tools such as lathes, milling machines, and drill presses.   They can be motorized or manually operated and can rotate at different speeds depending on the requirements of the operation.   The spindle is typically mounted on bearings to ensure smooth and accurate rotation and may include additional features such as tool holders or collets to securely hold the tool or workpiece in place.

  • Q Where is spindle motor?

    A The spindle motor is also called a high-speed motor, which refers to an AC motor with a rotational speed of 18,000-24000 rpm/min. Mainly used in wood, aluminum, stone, hardware, glass, PVC, and other industries.

  • Q What is a spindle motor?

    A
    A spindle motor is an electric motor that is used to rotate a disk or other cylindrical object, such as a hard disk drive or a CD/DVD drive.   It is a key component in the operation of many electronic devices that use spinning disks for data storage or reading.   The spindle motor is responsible for driving the rotation of the disk at a consistent speed, which allows the device to read and write data accurately.   The speed of the motor is typically controlled by a feedback mechanism that ensures that it remains constant even as the load on the motor changes.   Overall, the spindle motor plays an essential role in the reliable operation of many modern electronic devices.
    For those unfamiliar with what a spindle motor is, it is a motor that is designed to rotate at high speeds, most commonly used in applications such as CNC milling machines.    Like all motors, spindle motors can and will break suffering many of the same failure modes as other types of motors.

  • Q What spindle motors are used?

    A Electrical motors are most commonly used as spindle drives.  Depending on the requirements on the machine tool, 4 different types of spindle motors can be employed here: Water Cooled Spindle Motor, Air Cooled Spindle Motor, CNC ATC Spindle Motor and VFD CNC Spindle Motor.

  • Q What is a stepper motor used for?

    A
    A stepper motor is a type of electric motor that is used to precisely control its position and speed.  It is commonly used in a variety of industrial and consumer applications, such as robotics, automation, CNC machines, 3D printers, and more.
     
    Stepper motors work by converting electrical pulses into precise mechanical movements.  They have a rotor with teeth that align with a set of electromagnets, called stator coils.  By energizing the stator coils in a specific sequence, the motor can rotate in small, precise steps, allowing for accurate control of position and speed.
     
    One of the key advantages of stepper motors is their ability to maintain position without the need for a feedback sensor, which simplifies their control and reduces costs.  They are also known for their high torque at low speeds, making them well-suited for applications that require precise control over position and movement.
     
    Overall, stepper motors are a versatile and widely-used type of electric motor that offer precise control and accuracy, making them an ideal choice for many applications in various industries.

    The types of Stepper motors recommended by HOLRY are Hybrid Stepper Motor,Gearbox Stepping Motor,PM Stepper Motor,Special Stepper Motor,Closed Loop Stepper Motor.

  • Q Differences between brushed and brushless DC motors?

    A
    To keep the shaft of a DC motor rotating in the same direction, there is a need for a mechanism to switch the direction of the electric current flow once every half-rotation (a process called "commutation").  Brushed DC motors achieve this by mechanical means, using a commutator and brushes.
     
    However, because this mechanism relies on the brushes and commutator remaining in electrical contact as the shaft rotates, these parts tend to wear from friction over extended use.  In other words, they are consumable parts and require periodic maintenance.  Another problem is that this continuous electrical contact generates both electrical and acoustic noise.
     
    In contrast, brushless DC motors eliminate the need for brushes and commutator by instead incorporating an electronic circuit that detects the angular position of the shaft.  This also eliminates the associated maintenance, and reduce noise.

  • Q What is the difference between AC and DC brushless motor?

    A Brushless DC motors are similar to AC synchronous motors.  The major difference is that synchronous motors develop a sinusoidal back EMF, as compared to a rectangular, or trapezoidal, back EMF for brushless DC motors.  Both have stator created rotating magnetic fields producing torque in a magnetic rotor.

  • Q Which is better brushless vs brushed motor?

    A Brushless motors have significantly higher efficiency and performance, and a lower susceptibility to mechanical wear than their brushed counterparts.  Brushless motors offer several other advantages, including: Higher torque to weight ratio.  Increased torque per watt of power input (increased efficiency)

  • Q Why brushless motor is faster?

    A Brushless motors solve the limitations of brushed motors, providing much higher output power, smaller size and weight, better heat dissipation and efficiency, wider operating speed ranges, and very low electrical noise operation.  When it comes to torque and power, brushless motors can't be beat.

  • Q Why is a brushless motor better?

    A Because there are no brushes rubbing against anything, no energy is lost due to friction.  That means brushless motors are more energy-efficient than brushed drills and can run on batteries for up to 50 percent longer.

  • Q what is a brushless motor？

    A
    A brushless motor is an electric motor that operates without the use of brushes. It uses a series of magnets and electronically controlled commutation to produce rotational force. Unlike traditional electric motors, which use brushes and a commutator to switch the current direction and keep the rotor turning, brushless motors use electronic circuitry to control the rotation of the motor.
     
    Because there are no brushes to wear out, brushless motors are more efficient, reliable and have longer lifespans compared to brushed motors. They are commonly used in applications where high power and efficiency are required, such as in drones, electric vehicles, industrial machinery, and power tools. However, brushless motors are generally more expensive than brushed motors due to their advanced design and complexity.


    Types of Brushless Motor are:

  • Q What are different types of linear actuators?

    A There are three types of Linear Actuators used in manufacturing: Hydraulic, Pneumatic, and Electro-Mechanical.

  • Q What are linear and rotary actuators?

    A Linear actuators move an object or piece of equipment in a straight line. ... A rotary actuator produces a rotary motion via a shaft to control the speed, rotation and position of any attached equipment.

  • Q What do you mean by linear actuator?

    A What is a Linear Actuator? An electric linear actuator is a device that converts the rotational motion of an AC or DC motor into linear motion. It can provide both push and pull movements. This movement makes it possible to lift, drop, slide, adjust, tilt, push or pull objects with the simple push of a button.
