An electric motor is a type of electromechanical device that converts electrical energy into mechanical energy by producing rotational force through automated operations. The motor's functionality is primarily dependent on the interaction between electric and magnetic fields.
Electric motors typically consist of various components, including a central motor shaft, windings, bearings (used to reduce friction and wear), armature (located on either the rotor or stator), brushes (in DC motors), terminals, frame, and end shields.
There are two main types of electric motors: AC motors, which utilize alternating current as an input, and DC motors, which operate using direct current.
In the next video, we will show our different brushless motors. Most brushless motors use DC, and of course we also have brushless motors that use AC voltage. After watching the video, we will explain to you the classification of our brushless motors.
The principle of a DC motor is that there is a wire formed into a rectangle and suspended between the poles of a magnet. When DC power is supplied to the wire through a linked voltage battery, a temporary magnetic field is generated around the wire. This temporary magnetic field is the same as the permanent magnet. The magnetic fields interact, causing the wires to spin.
However, without a commutator, the wire stops and then reverses its direction of rotation. A commutator is a rotary connection that reverses the current every time the wire is flipped, ensuring that the wire continues to rotate in the same direction as long as current is flowing.
In the video we show different types of servo motors, feel free to contact us if you are interested. We have specialized in motor manufacturing for more than ten years and have rich experience. Our team is also quite professional and supports customized services.
Different manufacturers also have their own different ways of naming products. The following is the relevant classification of our servo motors. Of course, we can also match servo motors and also support customized services. If you are interested, please contact us.
When propagating alternating current (AC) through a wire, electrons do not travel in a consistent direction as they do with direct current (DC). Instead, they wiggle back and forth, transferring energy in a manner similar to Newton's Cradle.
AC is commonly used in power distribution systems for its efficiency over long distances and its ability to transmit high voltage with low current. This is because the back-and-forth motion of electrons creates an electrical field that can be transformed to increase voltage while keeping the current low.
The relationship between current and voltage is governed by electronics laws such as Ohm's Law (Resistance=Voltage/Current) and the Power Law (Power=Current x Voltage). Increasing voltage results in increased resistance, while decreasing current with constant voltage increases resistance.
AC motors are suitable for high-power appliances and machines that do not require precision, such as blenders and washing machines. While they can ramp up or down in speed, their efficiency is typically lower than that of DC motors due to energy lost to the magnetic field they generate.
This article lets you understand the main working principles between AC motors and DC motors and the classification of our motors, which type of motor may be more suitable for your application. As always, the best performing motor will depend on the specific characteristics of your application and your priorities, if you are unsure, let us know your needs and we can select the motor that suits you accordingly.
