Product Description:

The MAC90A-ZD-2-C/110-A-0/J1250 is an AC servo motor produced by Bosch Rexroth Indramat and supplied under the MAC AC Servo Motors series. The unit is built for analog drives and provides closed-loop motion for positioning tasks in automated machinery. A blocking brake is installed, allowing the shaft to hold a load when power is off, while the 110 mm centering diameter supports rigid flange mounting and maintains alignment with gearboxes or belt pulleys.

Its nominal operating speed reaches 2000 rpm, providing a suitable operating range for many positioning and speed-control applications. At standstill, the motor can deliver 3.7 Nm of torque while drawing a continuous current of 8.1 A; these values indicate how much static load the axis can resist without overheating. For rapid acceleration, the drive may supply a peak current of 53 A, providing short bursts of force without exceeding the motor’s thermal limits. The electromagnetic design provides a torque constant of 0.51 Nm/A, so each ampere of current delivered by the amplifier produces just over half a newton-meter of torque.

The stator windings have an inductance of 1.9 mH and a resistance of 1.85 Ω; these electrical values influence the current rise time and how quickly the control loop can change torque. The enclosure has an IP65 protection rating, shielding internal components against dust ingress and low-pressure water jets during washdown maintenance. The motor has a mass of 12.5 kg, while its rotor inertia of 20 × 10⁻⁴ kg·m² supports a balance between dynamic response and mechanical stability. A 24 mm shaft diameter transmits power to couplings, and the 45-minute thermal time constant indicates that the winding temperature changes gradually during cyclic operation.
