Motor Types and Technical Features
DWP series is the Hollow direct drive synchronous motor with high torque, low pulsation, and high efficiency.
Its bearing scheme is specially designed to withstand higher axial and radial loads.
The motor is equipped with a multi-turn absolute encoder, a serial communication mode, and an external battery to ensure accurate absolute position even during power failure.
