1MR160D-A040/S030

The Bosch Rexroth Indramat 1MR160D-A040/S030 from the 1MB High-Speed Asynchronous Motors series features a motor size 160 frame with a motor length D and an inside diameter of rotor 40 mm. This high-speed asynchronous spindle accepts a 171 V input supply and delivers a rated output power of 6.7 kW while drawing a rated current of 23.8 A in its 4B winding configuration. The unit generates a rated torque of 10 kW (4A winding) and is optimized for continuous operation at ambient temperatures up to +40 °C. With an electrical time constant defined by inductivity of 1.57 mH and resistivity of 0.182 Ω, the rotor–stator combination achieves precise dynamic response.

A rugged IP00 protection class housing underscores the need for a controlled environment, and the rotor’s 7.3 kg mass ensures mechanical stability within the main spindle assembly. Liquid cooling via an aluminum cooling jacket evacuates up to 1.8 kW of heat loss, requiring the machine builder to specify coolant flow, pressure, and cleanliness parameters. The motor’s design calls for dry, shock-free handling in line with the user manual, and all thermal loads are managed to maintain optimal winding temperatures.

Supplied by Wake Industrial with a one-year product replacement warranty, the 1MR160D-A040/S030 rotor is engineered for reliable, high-speed machining spindles. Proper integration of the cooling circuit and adherence to installation guidelines will ensure long service life and consistent performance in precision automation applications.
