●Meaning Of Torque Motor (DD motor)
1. Direct Driver - direct drive。
2. Due to the large torque, it is also called torque servo。
3. High performance embodied in technical indicators - high-quality products in servo product series。
●Product Principle
1. DD motor is literally understood as a direct drive motor, but in fact it is not an ordinary servo, but a
special AC motor with very complex structure, high precision and high performance. It is called direct
drive because it adopts the way of direct connection between the rotor and the moving carrier, and
other transition connections (reducer, coupling, etc.) are no longer used in the middle.
2. The structure of DD motor is divided into inner rotor and outer rotor. The centripetal bearing used
inside can bear a certain axial force. The angular resolution of the encoder is high, generally more
than 500000 PPR (PPR is the number of pulses per revolution). Due to the high-level manufacturing
process and high-precision measurement feedback, the positioning accuracy of this encoder can
reach the angle second level (1 degree = 3600 arcsec).
●Why Choose DD motor
1. High rigidity, compact structure and high efficiency。
2. DD motor has strong rigidity and hard characteristics compared with the load structure, so it has high
requirements for its driver。
3. The unique design of the hollow motor not only reduces its own inertia, but also provides customers with many
installation forms. The combined mechanical structure is more compact and the use efficiency is higher than
other methods.
