Product Description:

The MAC093A-0-PS-4-C/110-B-0/WI522LV is a servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. It is intended for analog drive systems where closed-loop speed and position regulation are required. In automated machinery, the unit converts drive commands from a servo amplifier into controlled torque and rotational motion for axes such as feeders, gantries, and packaging spindles. This operating role suits applications that require repeatable motion and stable response during frequent starts, stops, and speed changes.

Its centering flange is machined to 110 mm, providing a precise reference for alignment to gearboxes or adapter plates. The stator windings are cooled by natural convection, so heat leaves through the housing surface without fans or liquid circuits. At a nominal speed of 3000 rpm, the rotor can deliver rated torque while remaining within the motor’s thermal limits. The winding code PS indicates electrical characteristics that match analog MAC drives. A built-in tachogenerator produces 3 V/1000 rpm, giving the drive electronics a proportional velocity signal for speed regulation. Power conductors exit through a connector on side B, allowing cable routing opposite the load end in machines with rearward service access.

The motor uses the motor size 093 housing, and its compact motor length A helps keep the overall depth short for retrofit installations with limited rear clearance. Position control is supplied by an incremental encoder mounted in the standard orientation, and the tacho signal quality is standard for general-purpose servo loops. The motor has no blocking brake, so an external holding device is required when the load must remain fixed after power is removed. Leaving out an internal brake reduces drag and keeps rotor inertia lower during reversing or indexing duty.
