FAQ

  • Q How do you use a motor driver?

    A We use motor drivers to give high power to the motor by using a small voltage signal from a microcontroller or a control system. If the microprocessor transmits a HIGH input to the motor driver, The driver will rotate the motor in one direction keeping the one pin as HIGH and one pin as LOW.
  • Q What is motor and motor drive?

    A A motor is the mechanical or electrical device that generates the rotational or linear force used to power a machine. A drive is the electronic device that harnesses and controls the electrical energy sent to the motor. It is important to distinguish between motors and drives.
  • Q Why should you buy from us not from other suppliers?

    A Products conform to CE and ROHS standards, and have a good reputation at home and abroad. The company has a group of excellent, experienced management and technical personnel.
  • Q How do DC motor drivers work?

    A A DC motor controller manipulates the position, speed, or torque of a DC-powered motor and easily reverses, so the DC motor drive current runs in the opposite direction. Enjoy higher starting torque, quick starting and stopping, reversing, variable speeds with voltage input and more.
  • Q What is a motor driver?

    A The output form of the motor driver is output in digital form, so the PWM pulse modulator is used to control the speed of the motor, and the movement and direction of the motor are controlled by the current.
  • Q What is the main reason to use a stepper motor?

    A Essentially, stepper motors provide excellent speed control, precise positioning, and repeatability of motion. Also, stepper motors are very reliable because there are no contact brushes in the motor. This minimizes mechanical failure and maximizes the life of the motor. Moreover, stepper motors are more affordable than other motors and have a wide range of applications.
  • Q Why are stepper motors important?

    A Stepper motors can produce full, instantaneous torque - even from a standstill. This makes them very useful for motion control applications, where accuracy, repeatability, and power are paramount.
  • Q What is stepper motor explanation?

    A Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called "phases". By energizing each phase in sequence, the motor will rotate, one step at a time. With a computer controlled stepping you can achieve very precise positioning and/or speed control.
  • Q Why use gear reducer?

    A Speed reducers, also called gear reducers, are mechanical gadgets by and large utilized for two purposes. Gear reducers essential use is to duplicate the measure of torque produced by an information power source to expand the measure of usable work.
  • 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.
