Product Description:
The MAC90C-0-KD-3-C/110-A-D/S001 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. Designed for analog drives, it supplies closed-loop speed and position control to older drive amplifiers that rely on tachometer feedback rather than digital encoders. The compact frame has a 110 mm mounting pilot, allowing accurate alignment when the motor is coupled directly to a gearbox or mechanical load. Its sealed housing protects the stator in general-purpose automation environments where dust and water spray may be present.
A continuous phase current of 17.0 A sustains the rated shaft output and produces a continuous torque of 10.4 Nm up to the nominal speed of 2000 rpm. For rapid acceleration or transient load increases, the drive can supply a peak pulse current of 125 A without exceeding the motor’s thermal limits. The IP65 protection rating indicates that the housing prevents dust ingress and resists water jets, reducing the need for an additional enclosure in suitable industrial areas. Natural convection removes heat through the ribbed housing, while the motor’s mass of 23 kg helps store thermal energy and moderate temperature changes. The torque constant is 0.68 Nm/A, indicating the mechanical torque produced for each ampere of stator current. A winding inductance of 3.6 mH affects the current rise time and the response of the drive’s current regulator.
The motor has a thermal time constant of 60 minutes, so its temperature changes gradually during extended operation. Rotor inertia is 53 × 10⁻⁴ kg·m², providing moderate resistance to speed changes and helping smooth velocity regulation in printing or web-handling axes. A tachometer constant of 3 V/1000 rpm provides an analog speed signal to the controller. The winding resistance is 0.60 Ω, which contributes to copper losses as current passes through the stator. Power and feedback connectors are located on Side A, allowing cables to be routed from the same side of the motor housing. Natural convection cooling eliminates the need for an external fan, which reduces the number of auxiliary components required around the installation.
