The application range of micro motor and the introduction of the application area of micro motor

Micro motor is a kind of motor that applies the elastic vibration method of ultrasonic waves to obtain driving power, and then uses friction to drive the rotor and drive it. The following motor editor to introduce the types of micro-motors and the scope of application.

Micro-motors can be broadly divided into 3 categories in terms of structure.

1. Electromagnetic, the basic composition is similar to the common motor, including stator, rotor, armature winding, brush and other components, but the structure is extra compact.

2. Combination type, there are two common: the combination of the above-mentioned micro-motor; micro-motor and electronic circuit combination. For example, the combination of DC motor and sensor, the combination of X-direction and Y-direction linear motor, etc.

3. Non-electromagnetic type, the shape and structure of the same as the electromagnetic type, such as rotary products made of cylindrical, linear products made of square, but the internal structure varies greatly due to its different working principles.

Application range of micro motor

Mainly used in intelligent manufacturing, mechanical arm, medical equipment, intelligent doors and windows, miniature head, 3 degrees of freedom handheld stabilizer and all other small power constant speed and high torque equipment.

Application fields of micro motor.

1, aerospace field: aerospace vehicles are often in high vacuum, extreme temperature, strong radiation, can not be effectively lubricated and other harsh conditions, and the system weight requirements are strict, ultrasonic motor is the best choice of which drive.

2, precision instrumentation electromagnetic motor with gearbox deceleration to increase the torque, due to the existence of gear clearance and return error, it is difficult to achieve high positioning accuracy, and ultrasonic motor can be directly driven, and fast response, good control characteristics, can be used for precision instrumentation.

3, the robot's joint drive: using ultrasonic motor as the robot's joint drive, the fixed part of the joint and the moving part can be used as one with the stator and rotor of ultrasonic motor respectively, making the whole mechanism very compact.

4, electromagnetic interference is very strong or does not allow the occasion of electromagnetic interference: in the nuclear magnetic resonance environment and magnetic levitation train operating conditions, the electromagnetic motor can not work properly, but the ultrasonic motor can be competent.
