MAC090A-0-ZD-4-C/110-A-0/WI504L

The Bosch Rexroth Indramat MAC090A-0-ZD-4-C/110-A-0/WI504L in the MAC AC Servo Motors series by Bosch Rexroth Indramat combines compact design with robust performance, offering a winding inductance of 1.9 mH and a winding resistance of 1.85 ohms for precise current control. It delivers a continuous torque of 8.1 Nm (Continuous Current at Standstill) and supports a maximum peak of pulse current of 53 A for dynamic response. The motor spins up to a rated speed of 2000 rpm while maintaining thermal stability, and its protection rating of IP65 safeguards against dust and water ingress. Internally rated to Insulation Class F, it ensures long-term reliability in demanding environments.

Thermal management is optimized with a thermal time constant of 45 minutes, allowing sustained operation under load before the windings reach critical temperature. The housing is finished in a black prime coat (RAL 9005) with a maximum layer thickness of 40 µm, providing corrosion resistance and aesthetic uniformity. Weighing 12.5 kg, the motor features a 110 mm centering diameter for straightforward mounting and functions reliably across an operating temperature range of 0 to +45 °C. With a moment of inertia of 20 x 10^-4 kg·m², it balances inertia and responsiveness for high-precision positioning.

Feedback and integration options include built-in tacho feedback with incremental or mounted encoder variants, ensuring real-time speed monitoring and closed-loop accuracy. The unit interfaces seamlessly with TDM KDS or DSC drive controllers and requires operation by trained technicians to unlock its full potential. Note that this model does not include a holding brake; alternative variants are available if brake functionality is required.
