MAC041B-0-BS-3-E/050-B-1/S001

The Bosch Rexroth Indramat MAC041B-0-BS-3-E/050-B-1/S001 servo motor, part of the MAC AC Servo Motors series by Bosch Rexroth Indramat, delivers precise motion control with a nominal speed of 3000 min⁻¹ and robust torque generation. Under standard conditions it provides 3.5 Nm of continuous torque at standstill, with enhanced performance up to 5.0 Nm when surface cooling is applied. The motor’s modular design supports a compact rotor inertia of 20×10⁻⁴ kg·m², optimizing dynamic response in industrial automation tasks. Its IP65-rated enclosure ensures reliable operation in harsh environments, offering full protection against dust and water ingress. The combination of a high torque constant and advanced feedback makes the MAC041B-0-BS-3-E/050-B-1/S001 ideal for precision applications requiring repeatable speed and position control.

The MAC041B-0-BS-3-E/050-B-1/S001 incorporates multiple critical specifications to support demanding operational profiles. It features a torque constant at 20 °C of 0.34 Nm/A alongside a winding resistance of 0.56 Ω and winding inductance of 3.2 mH, facilitating controlled current dynamics and thermal distribution. The integrated tachogenerator offers a voltage constant of 0.0143 Vs/rad, enabling high-resolution speed feedback. Continuous current at standstill is rated at 11.4 A, extending to 16.3 A with surface cooling, while the motor can handle peak demands through a maximum pulse current of 76 A. The robust Class F insulation system supports ambient temperatures from 0 °C to +45 °C, maintaining electrical integrity and thermal resilience.

Operational durability is ensured by a thermal time constant of 45 min, reduced to 30 min under surface cooling conditions to prevent thermal overload during extended high-torque cycles. The IP65 protection category safeguards internal components, while the black prime coat finish (RAL 9005 housing finish) protects against corrosion in industrial settings. Weighing 12.5 kg, the motor balances structural rigidity with manageable mass for rapid acceleration profiles. The precise 0.34 Nm/A torque constant combined with the tachogenerator’s 0.0143 Vs/rad voltage constant supports smooth speed regulation and load compensation across the full speed range.

Integration with industrial controllers and servo drives is simplified by the standardized footprint and feedback interfaces of the MAC AC Servo Motors series. The MAC041B-0-BS-3-E/050-B-1/S001 is optimized for high-precision tasks in robotics, packaging machinery, CNC equipment, and assembly lines. Its IP65 rating and Class F insulation make it suitable for washdown processes and environments with fluctuating humidity. Bosch Rexroth Indramat’s proven design and comprehensive specification set provide a reliable foundation for automated systems requiring consistent performance and minimal downtime.
