Product Description:

The MAC090A-0-RD-3-D/110-A-0-S001 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it converts controller output into precise rotary motion for positioning tables, tool changers, and conveyor axes in automated machinery. A centering diameter of 110 mm supports accurate mounting, and a second shaft end at the rear provides another mechanical coupling point, while the integrated tachogenerator supplies velocity feedback to the drive.

During continuous operation, the motor produces a continuous standstill torque of 3.5 Nm while drawing a continuous standstill current of 11.4 A from the connected drive. Once the motor begins rotating, the rotor reaches a nominal speed of 3000 rpm, and the electromagnetic design provides a torque constant of 0.34 Nm/A for a predictable relationship between current and torque. The minimum conductor cross-section is 1.0 mm², and the power connector is located on side A for cable routing. The three-phase winding has an inductance of 3.2 mH and a resistance of 0.56 Ω. Its normal operating current is 9.3 A per phase. The motor has no blocking brake, so an external holding device is required when the shaft must remain stationary during a loss of power.

Transient loads are supported by a peak pulse current of 76 A, while a rotor inertia of 20 × 10⁻⁴ kg·m² supports responsive acceleration. Heat generated during these bursts dissipates through natural convection, and the motor has a thermal time constant of 45 min that indicates how quickly the winding system approaches thermal equilibrium. The IP65 protection category prevents dust from entering the housing and protects the motor against water jets. A total mass of 12.5 kg provides structural rigidity without placing excessive load on the mounting brackets. These operating characteristics support applications that require controlled motion under continuous and intermittent loading.
