Product Description:

The MAC93A-0-WS-2-C/110-B-0/S001 is an AC servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Designed for analog drives, it is installed in automation axes that require precise torque control without digital fieldbus infrastructure. By combining electromagnetic torque generation with tacho feedback, the unit closes a velocity loop directly at the drive, allowing stable positioning and speed regulation in machine tools, printing lines, and material-handling equipment.

Under continuous duty, the motor delivers a standstill torque of 9.2 Nm while drawing a continuous current of 11 A. Its nominal speed of 2000 rpm provides a practical operating range for processes that balance throughput and accuracy. The motor has a torque constant of 0.875 Nm/A, meaning each ampere supplied by the drive produces nearly one newton-meter of torque at the shaft. The housing carries an IP65 rating, so airborne dust and water jets do not reach the internal windings. Heat is removed solely through natural convection, eliminating the need for forced-air attachments. A centering diameter of 110 mm accommodates compatible mounting flanges, and analog tacho feedback delivers real-time velocity data to legacy controllers without digital encoders.

For short accelerations, the winding can accept a peak current of 54 A, providing high breakaway torque before thermal limits are reached. Electrical response is governed by a winding inductance of 16.0 mH and a winding resistance of 1.313 Ω; these values affect current rise time and copper losses in the drive circuit. The motor weighs 13.0 kg, and its rotor inertia of 22 × 10⁻⁴ kg·m² balances rapid response with load stability. A thermal time constant of 50 minutes indicates how gradually the internal temperature responds to load changes. Because the motor does not have a blocking brake, an external holding device or drive-applied torque is required to secure the load when power is removed.
