MAC AC Servo Motors
Rated 4.5 stars (14 total reviews)
The MAC093B-0-OS-4-C/110-B-0/WI561BX/S005 is a servo motor produced by Bosch Rexroth Indramat and delivered as part of the MAC AC Servo Motors series. Classified for analog drive systems, this motor converts electrical control signals into precise rotary motion for automated positioning, indexing, and velocity regulation tasks on production machinery in modern assembly lines.
In mechanical terms, the flange centering diameter is 110 mm, allowing direct alignment with gearboxes or mountings of the same pilot bore. Heat is released by Natural convection, so airflow around the housing must be unobstructed instead of being forced by an external fan. Shaft torque is transmitted through a DIN 6885 keyway, which standardizes coupling to pulleys or couplings. The motor reaches a nominal speed of 2000 min⁻¹, matching drive tuning tables for medium-inertia machine axes. The internal tachogenerator outputs 3 V/1000 min⁻¹, supplying the analogue drive with proportional velocity feedback, while the power conductors leave through a connector on side B to simplify cable routing inside vertical cabinets.
Position information is supplied by an incremental encoder mounted in the standard configuration, letting the control loop count pulses for precise angular displacement. The electromagnetic package follows winding code OS, which sets the voltage constant and current demand expected by the matching MAC drive module. Application planners should note the motor is shipped without a blocking brake; holding torque must therefore be provided by the drive or an external brake when the axis stops under gravity or static load. Motor size 093, length B, and the standard tacho quality complete this performance profile.
