Product Description:

The MAC092A-0-DD-1-B/095-B-0-I01250 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it converts command voltages from legacy drive amplifiers into controlled rotary motion for machine tool axes, packaging stations, and handling modules. The unit uses incremental encoder feedback for position and speed reporting, and it is supplied without a blocking brake, so mechanical clamping or drive torque must secure the load during power-off conditions.

Continuous torque of 1.50 Nm describes the steady shaft output available when the motor is held at its rated temperature, and it pairs with a continuous current requirement of 6.90 A from the analog drive amplifier. At a rated speed of 4000 rpm, the motor supports high rotational velocity for fast axis movement, while heat is removed by natural convection, eliminating the need for forced airflow or liquid cooling circuits. The torque constant of 0.240 Nm/A shows the relationship between current and torque output, which helps match the motor to a compatible amplifier and supports stable response during speed changes and load corrections.

A centering pilot of 95 mm provides a repeatable mounting reference when the housing is clamped to a machine plate, helping keep shaft alignment consistent with the driven mechanism. Rotor dynamics are influenced by an inertia of 8.70 × 10⁻⁴ kg·m², a value that supports quick acceleration and deceleration while maintaining smooth operation in analog control loops. Position feedback comes from an encoder mounted in the standard location and delivering 1250 cycles/rev, which gives the drive enough signal detail for precise speed monitoring and position tracking. Power is introduced through a connector on side B, keeping the cable exit clear of the motor shaft and simplifying routing where multiple axes are installed close together.
