1MS200H-4D-A2/S011

The Bosch Rexroth Indramat 1MS200H-4D-A2/S011 from the 1MB High-Speed Asynchronous Motors series features a Motor Length H, Motor Size 200, and dual Windings Code 4B and 4D configurations for advanced motion control applications. Designed for three-phase AC power input, this high-speed stator leverages a robust aluminum cooling jacket and a compact form factor. Its modular design ensures compatibility with recommended Bosch Rexroth accessories and controllers for seamless integration. Ideal for precision spindle systems, the 1MS200H-4D-A2/S011 is engineered to meet rigorous industrial standards.

Performance highlights include a maximum rotational speed of 6 000 rpm and a rated continuous torque of 309 Nm, with peak capability at the same value under short-term operation. A peak current of 128.2 A drives the stator’s 2.43 Nm/A torque constant, while an inductance of 2.55 mH ensures precise current-to-torque conversion. The machine’s 2 pole pairs architecture optimizes electromagnetic efficiency, and thermal management strategies minimize heat buildup during prolonged use. Every aspect of the stator is validated for reliability under dynamic loads in high-speed automation.

Thermal design incorporates a water cooling system absorbing a continuous heat loss of 3.1 kW through a dedicated coolant flow rate of 4.4 L/min and a 1.10 L duct volume. The stator operates within a relative humidity range of 5–95 % (non-condensing) and up to +40 °C ambient temperature without derating. At a net weight of 41 kg, the 1MS200H-4D-A2/S011 balances structural rigidity with manageable installation requirements, offering a dependable solution for high-performance spindle motor assemblies.
