MAC112B-1-GD-4-C/130-A-1/WA608XX

The Bosch Rexroth Indramat MAC112B-1-GD-4-C/130-A-1/WA608XX from the MAC AC Servo Motors series is a high-performance AC Servo Motor with a Motor Size 112 frame and Motor Length B housing. This plain-shaft design delivers a continuous standstill torque of 29 Nm at a current of 75 A, while withstanding peak demands up to a Maximum Pulse Current of 223 A. Surface-cooled via a top-mounted blower, the unit uses Surface Cooled technology to maintain optimal thermal conditions and ensure reliable operation. The built-in blocking brake engages with a Release Delay of Blocking Brake of 70 ms, enabling precise positioning even under abrupt load changes.

The integrated holding brake features a Clamping Delay of Holding Brake of 30 ms, allowing swift engagement during power interruptions. The rotor’s low inertia, with a Rotor Moment of Inertia of 120 x 10^-4 kgm2, supports rapid acceleration and deceleration cycles for high dynamic performance. Heat management is further enhanced by a Thermal Time Constant of 60 Minutes, ensuring stable temperature rise during prolonged duty. The motor’s electromagnetic characteristics include a Torque Constant at 20 degrees C of 0.430 Nm/A, Windings Inductance of 1.2 mH, and a Windings Resistance at 20 degrees C of 0.090 Ohm, guaranteeing precise current-to-torque conversion.

Designed for rugged industrial use, this MAC112B unit can be mounted in any orientation and requires only the manufacturer’s readymade cables to achieve an IP65 connector protection class. Lifetime-lubricated bearings and integrated thermal switches offer overload protection without additional maintenance. With its high power-to-weight ratio and brushless construction, the MAC112B-1-GD-4-C/130-A-1/WA608XX is ideal for applications demanding fast response, accurate positioning, and dependable operation.
