What Are the Application Areas of Coreless Motors?

The micro motor is composed of a stator, rotor, armature winding, brush, commutator and other components, wherein the rotor is composed of an iron core rotor and winding, and the hollow cup motor has no iron core, so it is also called a coreless dc motor. This motor is more special in the micro DC motor, it can be a brush motor, can also be made of brushless motor. This rotor structure completely eliminates the electrical energy loss caused by the formation of eddy currents in the iron core, while its weight and moment of inertia are greatly reduced, thereby reducing the mechanical energy loss of the rotor itself. Therefore, the coreless electric motor belongs to DC, permanent magnet, servo micro motor.

It has many advantages including high power density, high efficiency and energy saving, no torque lag, low starting torque, no radial force between the rotor and the stator, smooth speed curve, low noise, high peak torque; However, because there is no iron core support, the coil of the motor can only be made very thin, which will have the disadvantages of small torque and limited speed, and can not be used in application scenarios requiring high speed.

Coreless micro dc motor is widely used in robot field. The robot needs multi-axis movement, so it needs to install many motors, but the space is very limited, at this time you can use this motors, they are small, strong power, can meet the robot's multi-axis movement needs, while not taking up too much space. Secondly, it is also widely used in the aerospace field. A large number of motors are needed for flight attitude control and accurate positioning of spacecraft, and hollow cup motors have the advantages of high speed, high precision and high reliability, which can be qualified for this high-precision control task. In addition, it has also been widely used in the medical industry. Medical devices need accurate control and operation, and the motor can control the accuracy of up to 0.01 degrees, and can accurately control the operation of surgical instruments to ensure the safety and accuracy of surgery.
