1MS310B-6E-A1/S012

The 1MS310B-6E-A1/S012 from Bosch Rexroth Indramat is part of the high-performance 1MB High-Speed Asynchronous Motors series, featuring a motor size 310 frame and a motor length B configuration with a versatile windings code 6B, 6D, 6E. This stator draws a continuous current of 58 A to deliver a continuous torque of 260 Nm at 440 rpm and sustains a continuous power output of 12 kW. Its 1.5 m electrical cable provides straightforward connectivity to a three-phase power source, while the integrated aluminum cooling jacket and liquid cooling system dissipate up to 3.5 kW of excess heat. The robust design ensures consistent performance under demanding industrial conditions.

Engineered for precision and reliability, the 1MS310B-6E-A1/S012 stator exhibits a torque constant of 4.60 Nm/A and a winding resistance of 0.274 Ohm at 20 °C, paired with a winding inductance of 2.99 mH for smooth dynamic response. The unit is rated for an ambient temperature range of 0 to +40 °C without derating and can be installed at elevations up to 1000 m above sea level, beyond which efficiency gradually decreases. Featuring three pole pairs and a splashproof construction, this stator maintains operational integrity even in fluctuating environments, although it is not specifically protected against liquids or particulates.

Weighing in at 67 kg, the 1MS310B-6E-A1/S012 balances mass and compactness for high-speed applications, making it ideal for integration within 1MB kit spindle assemblies. Each motor ships with a comprehensive user manual and is backed by a one-year replacement warranty, ensuring minimal downtime and swift support. With its combination of thermal management, precise electrical characteristics, and proven corporate pedigree, this asynchronous motor delivers dependable torque density for advanced motion control systems.
