Product Description:

The MAC090B-0-PD-4-C-110-B-0-WI520LV-S001 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts commanded armature current into controlled torque and speed for automated machinery axes. This unit is intended for positioning tables, feeders, and processing spindles that require repeatable motion and integrated velocity feedback. Its compact construction supports installations where accurate rotary response is needed without adding separate external feedback hardware.

The motor’s centering flange is machined to 110 mm, allowing precise coaxial alignment with gearboxes or machine fixtures. Heat generated in the stator is removed through natural convection, so the housing can operate without forced airflow in enclosed cabinets. Under rated excitation, the rotor reaches 1500 rpm, which suits many standard ball screw and belt-drive ratios. A built-in tacho generator outputs 3 V/1000 rpm, giving the analog drive a proportional voltage for closed-loop speed control. Electrical characteristics follow the series-specific PD winding code, which sets the coil resistance, inductance, and current limits needed for stable continuous duty.

The motor has no blocking brake, so no holding torque is available when power is removed and vertical loads require an external holding method. Power conductors terminate through a connector on side B, helping keep cabling clear of the driven shaft and adjacent machine members. The feedback stack supports incremental or absolute encoder feedback with a tachogenerator, enabling either speed regulation alone or combined position control in legacy control racks. Shaft angle information is generated by an incremental encoder with standard mounting, and its pulses are qualified by a standard tacho quality rating that meets general-purpose control tolerances.
