1MS160E-4B-A1

The Bosch Rexroth Indramat 1MS160E-4B-A1 stator is an essential component of the 1MB High-Speed Asynchronous Motors series, designed to deliver reliable and consistent performance in demanding industrial environments. With a Motor Size of 160 and a Motor Length of E, this stator features a Windings Code of 4B, ensuring precise electromagnetic characteristics for optimal motor operation. Its primary function is to house the stator windings, creating a rotating magnetic field that interacts with the rotor to produce high-speed mechanical output for a wide range of automation and drive applications.

Engineered to meet stringent performance criteria, the 1MS160E-4B-A1 stator offers a rated torque of 33 Nm and achieves a rated speed of 3,000 RPM, translating to a rated power output of 3.5 kW at a rated current of 19 A. It operates on a nominal voltage of 176 V and can withstand a maximum current of 34.8 A while reaching a maximum speed of 4,000 RPM. The winding resistance is specified at 1.113 Ω with an inductance of 8 mH, and a torque constant of 2.43 Nm/A at 20 °C. The stator mass is 14.4 kg, complemented by a 9.4 kg rotor, providing a balanced rotor–stator assembly for stable high-speed rotation.

Designed for durability and ease of integration, this stator accommodates an ambient temperature range of 0 to 40 °C and storage and transport conditions between –20 to 80 °C with a relative humidity limit of 75 %. The unit carries an IP00 protection rating and insulation class F, ensuring reliable insulation performance. An aluminum cooling jacket surrounds the stator, allowing liquid coolant to absorb and dissipate heat during operation. Electrical connection is provided via a 1.5 m cable exiting the larger-diameter end. Shipped in its original packaging, the 1MS160E-4B-A1 stator is available worldwide with a one-year warranty. Its robust design, precise electromagnetic performance, and efficient cooling make it an ideal choice for high-speed, high-duty industrial drives and machinery.
