1MS160D-4B-A1

The Bosch Rexroth Indramat 1MS160D-4B-A1 stator is part of the 1MB High-Speed Asynchronous Motors series, designed for high-performance industrial drives. This 1MS160D-4B-A1 unit features a Motor Length of D and a Motor Size of 160, with a Windings Code of 4A, 4B. The primary function of this component is to house the stator winding assembly for high-speed three-phase asynchronous motors, providing the magnetic field basis for rotor excitation and ensuring precise torque generation across a wide speed range. Its robust construction and precise dimensional tolerances make it suitable for demanding automation and material handling applications.

This stator is equipped with an aluminum cooling jacket that enhances heat dissipation during continuous operation. A 1.5 meter cable is provided for electrical connection, terminating at the stator side with an enlarged output diameter for easy integration. The cable’s power conductors are grouped within a protective conduit, featuring a cross-section of AWG 12, an overall strand diameter of 14 mm, and a minimum bend radius of 56 mm to prevent conductor damage. Two embedded thermistors are mounted into the winding to monitor temperature: one active sensor and one spare for fail-safe protection. Installation best practices call for rounded or sleeved through-holes on the spindle housing to safeguard the cable during assembly.

Additional technical specifications include a rated speed of 2000 RPM and a maximum speed of 8000 RPM, supporting applications that demand rapid acceleration and deceleration. The stator supports a rated torque of 32 Nm, rated power of 67 kW, rated current of 23.8 A, and a maximum current of 53.28 A, ensuring consistent performance under variable load conditions. A clearly marked rating plate is supplied for easy identification and compliance verification. Shipped globally with a one-year warranty from Wake Industrial, the 1MS160D-4B-A1 stator offers enhanced longevity and reliability. In industrial settings, using this stator yields improved thermal efficiency, precise torque control, and reduced maintenance downtime.
