Product Description:

The MAC071B-0-TS-3-C/095-A-0 is an AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, it converts commanded current from a drive amplifier into precise torque and speed for automated machinery, including gear stages, linear actuators, and indexing tables. An integrated tachogenerator supports closed-loop velocity control, so the drive can correct speed changes as load conditions vary. This makes the motor a practical choice where stable analog feedback is needed without a digital communication interface.

Mechanical alignment is simplified by a centering diameter of 95 mm, allowing repeatable seating in flange interfaces common to mid-frame machines. Under rated operation, the rotor reaches 3000 rpm, a speed that balances dynamic response with bearing life in general-purpose positioning axes. Heat produced by copper losses is removed through natural convection, so no external blower or liquid circuit is required. Power conductors enter through a connector on side A, permitting cable routing parallel to the machine bed. For velocity feedback, the tachogenerator outputs 3 V/1000 rpm, giving the analog controller a proportional signal that scales linearly with shaft speed.

The motor has frame size 071 and motor length code B, which keep the housing compact for installations with limited space. The winding code is TS, which matches drive modules that supply the required phase voltage and current. The rotor is supplied without a blocking brake, so any holding torque must come from the drive or an external locking device. Tacho feedback is provided on the second shaft end, leaving the primary shaft available for couplings or pulleys while preserving the analog feedback arrangement. This layout helps when the load must be connected directly at the main shaft.
