Product Description:

The MAC090B-O-JD-4-C/110-A-0/WI520LV belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is an AC servo motor intended for use with analog drive amplifiers, where precise velocity and position loops are handled outside the motor. Within an automation line, the unit converts electrical control signals into controlled mechanical rotation that drives tooling, conveyors, or auxiliary axes. Because the control loops are closed in the amplifier, the motor can be integrated into systems that separate the power stage from the feedback evaluation electronics.

The flange has a centering diameter of 110 mm, allowing the housing to align directly with standardized mounting pilots on gearboxes or machine frames. Operation is specified without a blocking brake, so holding torque must be generated by the drive or an external brake when power is removed. The three-phase power leads exit through a connector on side A, keeping cable routing consistent in layouts that use a common cabinet orientation. Rotor speed feedback is supplied by absolute encoder tacho feedback, giving the connected controller the signals needed for closed-loop motion. A standard tacho quality rating indicates nominal ripple levels suited to general-purpose motion tasks.

Position control can also rely on the internal incremental encoder with standard mounting when the connected drive expects quadrature pulses rather than absolute code. The motor is classified as a motor for analog drives, so its electrical constants and feedback levels match legacy velocity-loop hardware. That hardware typically uses ±10 V command references for speed control and axis response. Using the onboard feedback devices gives the drive flexibility when matching older control platforms to different position-signal formats.
