Product Description:

The MAC090B-0-PD-4-C/110-A-0 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. This brushless unit is intended for analog drive systems where command voltages regulate torque and speed through closed-loop electronics. In automated production lines, it drives indexing tables, pick-and-place gantries, and other positioning axes that demand fast acceleration and repeatable velocity. The brushless design reduces commutator wear and supports repeated motion cycles in industrial service.

The motor housing provides a centering flange diameter of 110 mm, allowing alignment with gearboxes or machine frames while keeping shaft runout minimal. Heat generated by the stator is removed through natural convection, so mounting must permit unobstructed airflow around the surface ribs. Rotor position and speed are reported by an integrated sensor package with tacho feedback and an incremental or absolute encoder, permitting velocity and position loops from the same device. Under rated supply, the shaft reaches a nominal speed of 1500 rpm. Electrical power is delivered through a side-mounted connector on side A, which simplifies cable entry from the drive panel and reduces bending stress on the leads.

Winding code PD identifies the electrical constants used by the motor so the matched drive amplifier can deliver the intended torque range. The motor has no blocking brake, so applications that must hold a load at standstill need external braking or continuous drive torque. The built-in tachogenerator produces 3 V/1000 rpm, giving the controller a linear voltage proportional to speed, and its signal fidelity is standard for general motion duties. These feedback signals allow the paired analog drive to monitor motor behavior during operation and settling.
