Product Description:

The MAC090B-0PD-4C/110-B0/WI524LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts proportional voltage commands into precise torque and speed for automated machinery such as packaging stations and transfer lines. By pairing with legacy drive amplifiers, it provides a direct electromechanical interface for position and velocity control tasks.

Mechanically, the motor uses a 110 mm centering diameter that aligns the stator on the machine frame. During continuous operation, it can deliver 7.2 Nm of stall torque while drawing 11.9 A from the drive, and this pair indicates the continuous load the unit can hold without thermal drift. A torque constant of 0.67 Nm/A links output torque directly to phase current, allowing current-based tuning. The copper windings present a resistance of 0.97 Ω and an inductance of 5.1 mH, values that influence dynamic current rise and the sizing of the analog current loop. At its rated electrical frequency, the rotor reaches 2000 rpm, a speed suitable for medium-inertia axes. All of this is cooled solely by natural convection, so no auxiliary fan is required.

In transient conditions, the drive may command up to 86 A of pulse current, giving short bursts of acceleration that are shaped by a rotor inertia of 36 × 10⁻⁴ kg·m². Thermal soak is slow thanks to a time constant of 60 min, so brief overloads do not immediately push winding temperature to its limit. The motor itself weighs 18 kg, adding structural damping once bolted to the machine bed. Position feedback is supplied by an incremental encoder with 625 lines, mounted in the standard housing, which supports drive edge detection for velocity control. There is no blocking brake, so holding torque must come from the servo loop or an external clamp. Power cabling exits on side B, simplifying wiring where the drive sits to the right of the axis.
