Product Description:

The MAC092B-0-QD-1-B/095-B-2-101000/S013 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts electrical energy into controlled mechanical motion in positioning and velocity-regulated axes used in machining centers, handling modules, and automated assembly equipment. Its construction supports closed-loop operation, allowing drive controllers to modulate current and voltage so the shaft follows commanded profiles precisely under varying mechanical loads.

This model cools through natural convection, meaning heat is dissipated by surface radiation and ambient airflow, which removes the need for external fans but requires unimpeded mounting space. The shaft can reach a maximum usable speed of 4700 rpm, enabling rapid traverse moves while remaining within magnetic and bearing limits. At standstill, it develops 3.0 Nm of continuous torque, enough to hold or slowly index loads without overheating. Supplying that torque requires a standstill current of 11.9 A, which the drive must supply continuously while maintaining thermal margins. Dynamic response is helped by a rotor inertia of 16.0 kgcm², and this moderate inertia balances quick acceleration with stable regulation when coupled to light or medium-mass mechanisms.

A heavy-duty blocking brake is integrated to secure the shaft during power-off states or emergency stops, preventing back-driving on vertical or safety-critical axes. Accurate mechanical alignment is facilitated by a centering diameter of 95 mm, which mates with precision pilot registers on gearboxes or machine frames. Power conductors enter through a connector on side B, allowing cable routing away from moving components on side A. For feedback, the motor carries incremental encoder feedback, delivering pulse-based position and speed information to the analog controller so it can close the servo loop with consistent resolution.
