Product Description:

The MAC090B-0-JD-4-C/110-A-1/WI517LX is an AC servo motor produced by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. The unit serves as a drive element in position and velocity loops for analog-controlled automation axes. It converts electrical commands into controlled rotary motion for automated machinery. In typical motion systems, an external analog amplifier uses the motor to regulate axis movement during positioning and speed-controlled operation.

The motor body aligns with machine frames through a centering pilot of 110 mm, which keeps the stator concentric to the driven mechanics and helps limit runout. Ambient heat is removed by natural convection, so no external blower or liquid circuit is required and clearance should be left around the housing fins. Power is fed through a connector on side A, which groups the three phases and protective earth in one keyed plug on the same face as the drive shaft. Rotor position is reported by an incremental encoder with standard mounting, allowing the controller to derive velocity from pulse edges while using a reference marker once per revolution. A standard blocking brake is integrated, and its spring-applied friction disc locks the shaft when supply power is removed. This brake helps hold vertical loads at standstill without relying on servo torque.

Signal fidelity is reinforced by the tacho feedback, incremental, or absolute encoder interface, permitting systems that use analog velocity loops to verify speed independently of the primary encoder. This arrangement supports stable feedback handling when the controller must monitor both position and speed during closed-loop operation. Because the unit is a motor for analog drives, its wiring and voltage levels match legacy controller cards without additional interface converters. In dynamic duty cycles, the standard tacho quality keeps the tachogenerator error band within limits that help minimize speed ripple.
