Product Description:

The MDD025A-N-100-N2G-040PD0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it acts as the rotary actuator in compact handling equipment on assembly or packaging lines. Its 025 frame size and A length code keep weight low and installation depth short, so the drive can position the motor close to the load for accurate, high-speed motion. This arrangement suits short-travel axes and small indexing mechanisms where low moving mass helps preserve fast response.

Mechanical output is governed by a continuous standstill torque of 0.33 Nm, so the shaft can hold or slowly index small loads without overheating while the drive injects rated current. During dynamic operation, the rotor reaches a nominal speed of 10,000 rpm, matching applications that call for rapid acceleration and short cycle times. Precise concentric mounting is aided by a centering diameter of 40 mm, which fits standard Rexroth flange patterns and keeps radial runout within tolerance. All power and sensor conductors exit on the rear because the designated connection orientation is Side B, which can help keep cable routing away from the driven mechanism. The leads terminate through a connecting cable with coupling unit, so the housing does not need a separate terminal box.

Rotor position is reported by resolver feedback, giving the drive sinusoidal commutation signals even under electrical noise. For installations that demand clean environments, a configuration with a shaft seal helps prevent lubricant escape and blocks dust ingress at the front bearing. The single-ended shaft uses a keyway so pulleys or couplings can transmit torque without slippage, and the motor is supplied without a blocking brake, so any hold-position function must be provided by the controller or an external clamp. The motor also uses standard dynamic balancing, a standard housing, and a standard shaft end on side A. Because the motor has a single shaft end on side A, the opposite side remains available for the feedback assembly and bearing support.
