Product Description:

The MAC090A-0ZD-3-C/110-B-0/S001 is a brushless servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor for analog drives, it interfaces with voltage-controlled amplifiers to deliver position or speed control in automated transfer lines, machine tools, and handling systems. This configuration suits applications that depend on stable closed-loop motion rather than onboard digital control electronics. A centering diameter of 110 mm and a 130 mm mounting flange let the unit fit standard IEC mounting faces while supporting precise concentric alignment during installation.

At a nominal speed of 2000 rpm, the rotor delivers continuous motion that follows the reference from the analog controller and supports common axis speeds in industrial machinery. The standstill torque is 3.7 Nm, and the windings draw a standstill current of 8.1 A. Each ampere produces about 0.51 Nm/A of torque, which gives the amplifier a predictable current-to-torque relationship during low-speed control. The winding inductance is 1.9 mH, and winding resistance is 1.85 Ω, so the electrical characteristics remain suitable for stable servo response. The housing is sealed to IP65, which helps keep dust and low-pressure water jets away from internal components.

Cooling relies on natural convection, eliminating the need for forced-air ducts and simplifying cabinet or machine layout around the motor body. The rotor inertia is 20 × 10⁻⁴ kg·m², and the motor mass is 12.5 kg, which helps balance acceleration response with stable mechanical behavior. Short acceleration bursts can draw a peak pulse current of 53 A, and the 45-minute thermal time constant allows winding temperature to rise gradually during intermittent overloads instead of changing abruptly. The shaft diameter is 24 mm, so torque can be transferred directly to couplings or gearboxes without intermediate adapters, which helps limit torsional compliance in the drive train.
