Product Description:

The MAC093B-0-GS-4-C/110-A-3/WI522LV/S00 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is a motor for analog drives that converts drive commands into precise mechanical rotation for positioning, conveying, or forming tasks in automated equipment. The model integrates an extra heavy-duty blocking brake so machinery can hold load position whenever power is removed, and it can use either tacho feedback or encoder feedback to report speed and position to the drive controller during closed-loop operation. This combination suits analog motion systems that need accurate speed control together with dependable holding at standstill.

The blocking brake develops 22 Nm of static torque, giving sufficient holding force for medium-inertia axes. This brake arrangement helps the axis remain stationary between moves or during a loss of power. A centering diameter of 110 mm aligns the housing with standard mounting interfaces so the shaft remains concentric with connected mechanics. Heat is removed only by natural convection, eliminating the need for external blowers and requiring free airflow around the frame. At its nominal speed of 4000 rpm, the motor delivers rated output while the tachogenerator produces a proportional feedback voltage. Power enters through a single connector on side A, which simplifies cable routing inside a cabinet and keeps the opposite face clear for mechanical attachments.

An incremental encoder with standard mounting supplies position data and supports high-resolution commutation for the drive. Using both feedback paths lets the motor support position tracking and analog speed regulation in the same installation. The tachogenerator outputs 1.5 V/1000 rpm, a level calibrated for analog velocity loops used in legacy drive amplifiers. The winding design follows code GS, which matches coil impedance and thermal limits to compatible Indramat drive cards. The motor uses size code 093 and length designation B, giving a balanced ratio of torque to inertia for mid-range axes that require short acceleration times.
