Product Description:

The MAC041B-0-QS-2-E/050-B-0 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is configured as a motor for analog drives and is intended for axis modules that use analog command signals. The motor converts regulated current from a compatible servo amplifier into controlled rotary motion for pick-and-place arms, indexing tables, and other positioning equipment. Its responsive operation supports applications that require frequent acceleration, deceleration, and changes in rotational direction during automated production cycles.

Thermal management relies on natural convection, allowing heat to dissipate through the housing fins without an auxiliary blower. This cooling method reduces operating noise and eliminates the airflow connections associated with forced-air systems. Position and speed signals originate from integrated tacho feedback, which supplies a proportional voltage to a compatible analog servo amplifier for real-time motion control. The motor has no blocking brake, so an external clamp, mechanical stop, or drive-generated holding torque is required when a stationary load could move after power is removed. Suspended and gravity-loaded axes should therefore include a separate means of preventing unintended movement while the motor is not producing torque.

The motor has a frame size of 041 and a frame length of B, providing a compact housing with low rotor inertia for rapid acceleration. Power conductors terminate at a connector on side B, allowing the cable bundle to be routed alongside the motor body in installations with limited clearance. The connector position can help keep wiring away from the output shaft, coupling, and nearby moving components. Its compact dimensions make the motor suitable for closely spaced machine axes where available mounting room is restricted. Compatible analog control equipment can use the feedback voltage to correct speed deviations caused by changing loads, while the servo amplifier regulates current to maintain the commanded motion profile.
