Product Description:
The MAC090B-0-PD-1-B/110-A-1/-I01250 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It converts electrical command signals from drive controllers into controlled rotary motion for indexing tables, gantry axes, and similar automated machinery. When used in closed-loop motion tasks, it supports repeatable speed and position control during continuous industrial operation.
Its centering flange diameter is 110 mm, allowing direct seating in precision-bored mounting plates without shims. Heat generated in the stator is dissipated through natural convection, so no external blower or coolant piping is required. Rotor position is monitored by an incremental encoder feedback device that feeds pulse trains to the drive electronics for real-time regulation. The motor reaches a nominal speed of 1500 rpm, matching machinery that operates through speed-controlled converters. An internal tachogenerator outputs 3 V/1000 rpm, giving the analog controller a proportional velocity signal. During idle or power-off conditions, a standard blocking brake holds the shaft to prevent uncommanded motion.
The power cables exit through a connector on side A, simplifying cabinet layouts by keeping high-voltage wiring on one face of the housing. Electrical characteristics follow the PD winding code, indicating coil resistance and inductance suited to medium-current, low-speed operation. The unit is supplied as a motor for analog drives, permitting direct connection to legacy current-loop amplifiers without digital fieldbus adaptation. A standard mounting arrangement keeps the feedback device and flange-hole orientation consistent across the MAC family. This layout suits retrofit installations where existing analog control architecture remains in service and predictable cable routing is important.
