Dental endo motor type and application range
A dental endo motor is a motor that uses ultrasonic elastic vibration to obtain driving power, and then uses friction to drive the rotor to drive the motor. The following editor will introduce the types and applications of dental endo motors.
dental endo motors can be roughly divided into three categories in structure:
1. Electromagnetic
The basic composition is similar to that of ordinary motors, including stators, rotors, armature windings, brushes and other components, but the structure is extremely compact.
2. Combined
There are two common ones: the combination of the above-mentioned various micro motors; the combination of micro motors and electronic circuits. For example, the combination of DC motor and sensor, the combination of X direction and Y direction linear motor, etc.
3. Non-electromagnetic
The external structure is the same as the electromagnetic type. For example, rotating products are made into cylindrical shape, and linear products are made into square shape, but the internal structure is very different due to different working principles.
Application range of dental endo motor
Mainly used in all low-power, constant-speed and high-torque equipment such as smart manufacturing, robotic arms, medical equipment, smart doors and windows, miniature pan-tilts, and 3-DOF handheld stabilizers.
Application areas of dental endo motors:
1. Aerospace: Aerospace vehicles are often exposed to harsh conditions such as high vacuum, extreme temperature, strong radiation, and ineffective lubrication, and require strict system weight. Ultrasonic motors are the best choice for drivers.
2. Precision instrumentation electromagnetic motors use gearbox deceleration to increase torque. Due to the gear gap and return error, it is difficult to achieve high positioning accuracy. Ultrasonic motors can directly drive, and have fast response and good control characteristics. They can be used for precision Instrumentation.
3. Joint drive of the robot: The ultrasonic motor is used as the joint driver of the robot, and the fixed part and the moving part of the joint can be integrated with the stator and rotor of the ultrasonic motor respectively, making the whole mechanism very compact.
