Product Description:

The MAC093A-0-LS-4-C/110-B-2 is a servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it supplies closed-loop speed and position control to transfer lines, packaging axes, and general machinery where electrical drive amplifiers still operate with analog command signals. Its form factor uses motor size 093 and the compact length code A, which gives the motor a consistent footprint in existing machine layouts. The blocking brake and feedback options support safe holding and accurate motion during repeated industrial duty.

The motor is equipped with a heavy-duty blocking brake that secures the shaft during power-off situations. This brake can resist static loads up to 14 Nm, so vertical loads remain stable when the drive is disabled. Mounting alignment is aided by a centering diameter of 110 mm, which helps position the motor concentrically on gearboxes or adapter plates. Heat is dissipated through natural convection, so no external blower is required and cabinet airflow remains simple. During operation, the rotor can reach a nominal speed of 4000 rpm, providing enough headroom for fast cycle duties without overspeeding the feedback system.

Tacho feedback is delivered as incremental or absolute encoder feedback, giving the drive electronics either pulse trains for velocity loops or absolute data for precise positioning. At rated speed, the tacho generates 1.5 V/1000 rpm, a scaling factor the analog drive card uses to compare commanded and actual speed. Power conductors exit through a connector on side B, which helps keep cables away from the machine front. The LS winding matches the motor to standard analog amplifiers through its resistance and inductance values, and tacho quality is listed as standard for routine velocity regulation.
