Product Description:

The MAC90B-0-PD-2-C/110-A-1 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it receives current-loop commands from a matching amplifier and converts them into controlled torque and velocity. In automated machinery, this unit positions tooling, transports material, or follows interpolated paths where repeatable motion and rapid dynamic response are required. This operating style suits packaging equipment, transfer systems, and other motion axes that rely on smooth starts and accurate speed control.

At standstill, the rotor can generate a continuous torque of 7.2 Nm while drawing a continuous current of 11.9 A; these steady-state values indicate the heat load that must be removed through the natural-convection housing. Under rated operating conditions, the shaft reaches a nominal speed of 2000 min⁻¹, and short acceleration bursts are supported by a peak pulse current of 86 A. Mechanical alignment is simplified by a centering diameter of 110 mm. The housing has an IP65 protection rating, which helps keep out dust and water jets in typical plant environments, and the power connection is routed on side A to keep cable runs clear of feedback connectors.

A torque constant of 0.67 Nm/A links drive current to developed torque, which helps the amplifier respond predictably during commanded load changes. For static holding, the integrated brake supplies 6.5 Nm of torque and uses a nominal coil current of 0.7 A, allowing gravity-loaded axes to remain locked when the drive is disabled. Thermal behavior follows a time constant of 60 min, which helps describe internal temperature rise during extended duty. The tacho voltage constant is 3 V/1000 rpm, while the winding inductance is 5.1 mH and the resistance is 0.97 Ω, so the matching amplifier must account for the motor’s electrical response during startup and speed changes.
