Product Description:

The MAC63C-0-MS-2-C/095-A-0/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drive systems, this motor converts controlled electrical current into precise rotary motion for positioning, velocity, or torque loops in industrial automation assemblies such as pick-and-place units, packaging machinery, and textile equipment. Its frame integrates a 95 mm centering pilot and a keyed output shaft for repeatable mechanical coupling, while fanless natural convection cooling keeps the housing temperature within allowable limits during continuous duty.

During rated operation, the motor reaches a nominal speed of 3500 rpm, allowing fast cycle execution without overspeed margins. At standstill, it can deliver a torque of 2.1 Nm while drawing a continuous current of 4.1 A. The electromagnetic design produces approximately 0.51 Nm/A of torque per ampere, so current commands from the analog drive can be scaled directly into mechanical output. For brief accelerations or load peaks, the winding safely accepts a pulse current of up to 22 A before thermal limits are approached. A rotor inertia of 4.0 × 10⁻⁴ kg·m² supports quick response and stable low-speed operation, and the 5 × 5 × 22 mm keyway provides positive shaft coupling.

Electrical parameters guide system matching. The phase resistance is 2.8 Ω, and the winding inductance is 3.2 mH, so the motor presents a modest load to the drive’s current regulators and supports smooth analog control. Thermal modeling is simplified by a time constant of 30 min, indicating that temperature changes are gradual under varying duty cycles. Total mass is 4.6 kg, so mounting brackets can remain compact. Additional features include a tacho generator that outputs 1.5 V per 1000 rpm for speed feedback and a shaft sealing system rated IP50 against dust ingress.
