Product Description:

Bosch Rexroth Indramat developed the MAC090B-0-PD-1-B/110-A-0/I01000/S001 as a rotary actuator within the MAC AC Servo Motors series, aimed at precise position and velocity regulation in industrial automation. Designed for coupling to analog servo amplifiers, the unit converts electrical commands into controlled torque on machine-tool, packaging, and material-handling axes. Its electromechanical build balances thermal loading, mounting stiffness, and feedback resolution so that repeatable motion cycles can be sustained throughout long-duty production.

The motor seats against a housing shoulder sized at 110 mm to center the flange and maintain runout limits once bolted to the machine frame. Heat generated by copper losses leaves the stator through natural convection, removing the need for external blowers or liquid plates and simplifying cabinet layouts. Rotor position is reported by incremental encoder feedback, enabling fine speed loops and quick phase alignment during startup. Under nominal loading, the shaft reaches 1500 rpm, a reference speed that matches common gear ratios in transfer lines. Power conductors reach the stator windings through a connector on side A, and this plug orientation keeps high-voltage wiring away from feedback cabling on the opposite face. For velocity observers that still rely on analog tachometers, the design provides a proportional signal of 3 V/1000 rpm at the dedicated tacho terminals.

Because the motor has no blocking brake, stationary holding torque must be supplied by the drive or an external clamp whenever vertical or overhung loads are involved. The unit is a motor for analog drives, so its voltage constants, tachometer output, and encoder pulse count align with legacy analog proportional controllers rather than fully digital bus systems. Winding code PD identifies the resistance and inductance set chosen for medium-voltage operation, allowing flexibility when matching the motor to various amplifier current ratings.
