Product Description:

Bosch Rexroth Indramat manufactures the MAC90C-0-KD-1-B/110-A-0/J625/S01 in the MAC AC Servo Motors series. This AC synchronous unit is paired with analog drive amplifiers, where it converts commanded phase currents into mechanical motion for positioning tables, presses, and similar equipment. The motor accepts its armature power through terminals on Side A, integrates a 110 mm centering pilot for flange alignment, and relies on natural convection so no external blower is required inside the automation cabinet. It is suited to machine axes that need repeatable rotary output from a flange-mounted motor.

The motor’s regulated output begins with a nominal shaft speed of 2000 rpm, allowing standard 50 Hz or 60 Hz control loops to reach full velocity without field weakening. At standstill it draws 17.0 A and produces 10.4 Nm of holding torque, so the energized axis can resist static load without brake assistance. The electromagnetic design yields a torque constant of 0.68 Nm/A, which means each ampere of phase current produces a predictable increase in torque for smooth response. For rapid indexing moves, the windings may accept a peak pulse of 125 A, providing short bursts of acceleration without exceeding thermal limits. This current reserve supports quick starts and short acceleration ramps on intermittent-duty axes.

The enclosure carries an IP65 rating, which helps block dust ingress and low-pressure water jets in industrial service. Copper losses are moderated by a winding inductance of 3.6 mH and a winding resistance of 0.60 Ohm, and those values influence current rise time and the voltage demand placed on the analog amplifier. Stored heat dissipates over a 60 min thermal time constant, so the housing does not shed temperature changes instantly after a load shift. The matte RAL 9005 housing finish gives the motor a subdued exterior appearance on machine frames. Operation is permitted up to 1000 m above sea level, allowing full performance in most plant elevations without derating.
