Product Description:

The MDD025A-N-100-N2K-040GC1 synchronous motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed for digital drive controllers, it converts drive current into mechanical rotation on compact positioning axes in assembly, test, and handling equipment. The unit integrates motor feedback for closed-loop motion control, so the drive can monitor rotor position during start-up and normal operation. Its housing and rotor are balanced to the manufacturer's standard, which helps the motor run smoothly in compact machines that operate with frequent acceleration and deceleration. Its small format suits servo axes where installation space is limited and responsive motion is required.

Mechanical connection is centered by a 40 mm pilot, and all power and feedback conductors exit on Side A, which helps keep cable routing orderly in narrow cabinets and crowded machine frames. A factory-fitted connecting cable with coupling unit seals the motor interface against moisture and also provides strain relief at the cable entry point. High-speed operation is supported by a nominal speed of 10000 rpm, allowing rapid traverse and quick speed changes on small axes. At standstill, the motor can deliver 0.33 Nm of continuous torque for light holding duty and stable low-speed positioning.

An internal brake supplies 1.0 Nm of static torque and secures the load when the axis is disabled or power is removed. Rotor position is reported through resolver feedback, which resists electrical noise and supports stable feedback across the full speed range. The motor uses a plain shaft for couplings such as pulleys or friction wheels, and it is built with a shaft seal to retain lubricant and block fine dust. Standard balancing, the compact 025 frame size, and motor length code A keep mass and inertia low for small rotary units and short-travel linear stages.
