Product Description:

The MAC090B-0-P-D-2-C/110-A-0 is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. It is intended for analog drive controllers where closed-loop velocity and position regulation are required on machine tools, packaging lines, or material-handling axes. Natural convection removes heat, so no external blower is needed, and the IP65 housing protects the stator and feedback elements from dust and water in general factory environments. Its design suits axes that rely on stable analog command processing and integrated motor feedback during continuous industrial operation.

This model delivers a nominal shaft speed of 2000 rpm, allowing mid-range spindle or feed rates without overspeeding the mechanical system. When the rotor is locked, it can generate up to 7.2 Nm of stall torque, and that torque is achieved at a continuous phase current of 11.9 A. The electromagnetic coupling between the windings and magnets is characterized by a torque constant of 0.67 Nm/A, so each ampere commanded by the drive produces about two-thirds of a newton-meter. Copper loss at standstill is governed by a phase resistance of 0.97 Ω, which helps determine thermal rise and amplifier current limits. That electrical relationship also affects voltage demand as speed rises when the motor is paired with an analog amplifier.

For dynamic events such as acceleration or rapid indexing, the drive may supply up to 86 A of peak pulse current, which broadens the usable torque range beyond its continuous limit. The rotor inertia of 36 × 10⁻⁴ kg·m² balances quick response with stable load coupling, and a thermal time constant of 60 min shows that the 18 kg frame heats gradually under sustained load. Additional motor characteristics include 5.1 mH of winding inductance, a 110 mm pilot diameter, and tachogenerator feedback for velocity sensing. The pilot diameter helps center the motor on the machine flange, and the feedback signal gives the controller a direct speed reference for stable loop behavior.
