Product Description:

The MAC090B-0-JD-2-C/110-A-1 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed to pair with analog drive controllers, this unit supplies accurate rotary power to linear stages, indexing conveyors, and other electromechanical loads common in automated assembly lines. Its role in industrial automation is to translate reference commands into stable shaft rotation, supporting repeatable positioning and velocity profiles during continuous or cyclic machine operation.

The motor body provides a centering pilot of 110 mm, allowing precise seating against gearboxes or machine frames without additional shimming. Heat produced by the stator is removed through natural convection, so operation does not rely on a forced-air blower. Electrical power arrives through a connector on side A, which keeps cable egress on the same face as the drive cabinet in typical mounting orientations. For velocity regulation, the unit ships with tachometer feedback, feeding an analog tachometer signal back to the controller for closed-loop speed correction. A standard blocking brake is integrated to hold the shaft when power is removed, avoiding drift on vertical or overhung loads.

This model is classified as a motor for analog drives, so its winding impedance and sensor scale align with legacy current-controlled amplifiers that use tachometer feedback rather than digital encoders. The unit uses standard tacho quality, which provides a linear voltage-per-speed characteristic suitable for proportional gain settings used in classic PI regulators. When the brake is released and the cooling path remains unobstructed, the 90-frame construction can maintain thermal limits during continuous duty, and the mounting geometry supports straightforward installation in compact machine assemblies.
