Product Description:

The MAC90C-0-KD-4-C/110-A-0/WI518L/S001 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for use with analog drive amplifiers, it converts current commands into precise rotary motion for axes in conveyor assemblies, machining centers, and pick-and-place systems. The unit forms the electromechanical interface between the power stage and the load, delivering controllable speed and torque during continuous or cyclic industrial duty cycles.

At standstill, the motor sustains a continuous shaft torque of 10.4 Nm while drawing a phase current of 17.0 A. When accelerated, it can accept peak pulse currents of up to 125 A, providing a short-term torque reserve for rapid indexing moves. Under rated operating conditions, the rotor turns at 2000 rpm, a speed that aligns with common gearbox ratios used on material-handling equipment. Electrical losses are moderated by a phase resistance of 0.60 Ω at 20 °C and an inductance of 3.6 mH, providing a time constant that supports smooth current regulation from analog drives. The magnetic design produces a torque constant of 0.68 Nm/A, while the steel rotor has an inertia of 0.0053 kg·m² to balance dynamic response with load stability. A thermal time constant of 60 minutes indicates how long the motor takes to approach a steady operating temperature under a constant load. Tacho feedback supplies a velocity signal to the controller, supporting closed-loop speed regulation throughout the motor’s operating range.

A centering diameter of 110 mm aligns the housing with standard flange patterns and supports accurate mechanical installation. The frame weighs 23 kg, so the mounting points must support the static load and the dynamic forces produced during acceleration. Cooling relies on natural convection, which requires unobstructed airflow around the ribbed casing when the motor is installed in a cabinet. Shaft position is monitored by a factory-installed incremental encoder that returns incremental position signals to the controller. The encoder complements the tacho feedback by providing the information needed for precise positioning. Its feedback wiring is routed through a shielded INS 108/02 connector to help protect the signals from electrical interference.
