Product Description:

The MAC92B-0-QD-2-C/95-A-0 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is a brushless servomotor intended for analog drive systems, where precise velocity and torque loops are closed in the drive electronics rather than the controller. In industrial automation, the unit supplies rotary motion for positioning tables, packaging axes, and material-handling spindles that need repeatable speed tracking and fast response. Its operating concept suits machines that rely on the external amplifier to regulate motion continuously during changing load conditions.

At standstill, the motor can accept a continuous current of 11.90 A, and this current yields a sustained torque of 3.00 Nm while the winding temperature remains within its rated range. Under rated excitation, the rotor reaches 4000 rpm, which supports fast axis movement in compact servo applications. Torque production scales with phase current at an electromagnetic coefficient of 0.280 Nm/A, making current feedback a direct indicator of mechanical output. For analog speed regulation, the built-in tacho generator produces 1.5 V/1000 rpm as a linear feedback signal. This arrangement supports stable low-speed control as well as quick response during acceleration and deceleration.

The rotor’s mass moment of 0.0016 kg·m² helps limit overshoot when the servo is commanded to accelerate or reverse, and it also influences gain settings in high-bandwidth applications. Three stator windings arranged as three electrical phases provide symmetrical torque production and allow connection to standard three-phase power stages. This layout helps maintain smooth rotation across the speed range and supports consistent electromagnetic balance in the motor. Because it is specified as a motor for analog drives, the unit pairs with amplifiers that use proportional voltage or current commands rather than fieldbus-based control. That operating method suits systems that depend on direct interaction between amplifier output and motor response.
