Product Description:
The MMD022A-030-EG1-KN is a compact synchronous motor manufactured by Bosch Rexroth Indramat as part of the MMD Synchronous Motors series. It functions as a rotary actuator for positioning, indexing, and velocity control in automated machinery where closed-loop drives convert electrical commands into repeatable shaft motion. A plain shaft connects directly to couplings or gear stages, and an integrated holding brake keeps the axis in place during power-off intervals. This layout suits compact pick-and-place units, miniature gantries, and assembly stations that need accurate starts, stops, and quick direction changes in limited installation space.
At standstill, the rotor delivers a continuous torque of 0.64 Nm, and winding type 030 supports a maximum shaft speed of 5000 rpm. The square mounting flange measures 70 mm, and a centering diameter of 50 mm keeps the housing aligned with gearheads and machine plates. Power and feedback conductors exit on the A-side through a plug with a 25 cm lead, which helps simplify cable routing in tight enclosures. The enclosure has an IP65 rating to resist dust and low-pressure water jets during normal industrial use. The motor has a nominal speed of 3000 rpm, and length code A keeps the mass at 1.4 kg for lightweight axis designs.
Position data are generated by an incremental encoder that provides 2,500 increments per revolution for drive commutation and fine motion profiling. The holding brake produces 1.3 Nm of static torque and is released electrically, and its coil draws 24 V / 0.4 A during energization. For short acceleration bursts, the magnetic circuit can produce up to 1.91 Nm without exceeding thermal limits. A sealing ring around the 11 mm plain shaft helps prevent lubricant leakage. The encoder and brake combination supports stable low-speed positioning and secure load holding when the drive is not actively supplying torque.
