MMD022A-030-EG1-KN

The Bosch Rexroth Indramat MMD022A-030-EG1-KN from the MMD Synchronous Motors Series features a motor size of 22 with a winding code of 030 and length code A in a compact 128 mm frame. This servomotor is equipped with an incremental encoder, a plain shaft, and a fully integrated holding brake to ensure precise positioning and safe stops. Designed for use with Rexroth’s DM01.1-W0 22 servo drive controller, the motor interfaces via a plug connector with a 25 cm cable to the A-site for streamlined installation. Every unit undergoes a no-load trial run to verify that LED indicators function correctly and to confirm the motor is free of mechanical loads prior to commissioning.

Under continuous operation, the MMD022A delivers a continuous torque of 0.64 Nm at standstill and spins up to a nominal motor speed of 3,000 min⁻¹ with exceptional smoothness. The rotor inertia is 0.2×10⁻⁴ kg·m² (with brake fitted), and the load inertia must be kept below 30 times the motor’s inertia to preserve control loop stability. Its rugged IP65 protection category housing shields the output shaft, brake, feedback cable, and power cable from dust and liquids. The maximum allowable wiring length for input/output connections is 3 m to ensure signal integrity and comply with EMC guidelines.

Integration into automated systems is facilitated by the included 270 μF capacitor storing 8.91 J of energy and a built-in BRK-OFF signal that defaults to OFF when protection functions are active. The companion servo driver provides 200 W output power with a three-phase continuous input current rating of 1.1 A and an accuracy of ±2 % (5 mV), allowing fine-tuned torque control. With a total motor weight of 1.4 kg, this MMD servomotor offers a high power-to-mass ratio, making it ideal for space-constrained, high-precision applications.
