Product Description:

The MAC093C-0-FS-3-C/110-B-2/S001 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 commanded current into controlled shaft torque for position and speed regulation in automated machinery. The model carries the 093 frame size with the C length code and seats into a 110 mm centering pilot for rigid mounting. Natural convection removes the heat generated by copper losses, and a heavy-duty blocking brake on the second shaft end secures the load whenever drive power is disabled.

At standstill the motor develops 19.5 Nm while drawing 35 A, giving a useful reference for drive amplifier sizing during continuous holding duty. The electromagnetic design delivers rated output up to 3000 rpm, and the coupling produces 0.579 Nm/A, so commanded current translates linearly into shaft torque. A maximum demand of 173 A is tolerated for short pulses, enabling rapid acceleration when required by the machine cycle. The 42 × 10⁻⁴ kg·m² rotor inertia and the 3.6 × 10⁻⁴ kg·m² brake inertia influence the system's dynamic response, while winding code FS, a second-end tachofeedback arrangement, and a standard 3 V/1000 rpm tacho signal furnish the analog controller with real-time speed data.

The holding system operates from 24 VDC and applies 14 Nm through the heavy-duty brake, with a 30 ms clamping delay and a 70 ms release delay for repeatable engagement sequencing. The motor has a phase inductance of 2.9 mH and a copper path resistance of 0.175 Ω, and these values affect current ripple and drive regulator tuning. The winding mass absorbs heat for a 50 min thermal time constant, allowing the motor to ride through intermittent overloads when cooled only by ambient airflow. All conductors arrive on a connector on side B, matching drive-cabinet layouts that prefer cable exits opposite the load.
