1MR200D-B085/S001

The Bosch Rexroth Indramat 1MR200D-B085/S001 from the 1MB High-Speed Asynchronous Motors series combines precision engineering with versatile performance for high-speed spindle and direct-drive applications. This motor features a Motor Size 200 frame and a Motor Length D stator housing, accommodating an Inside Diameter of Rotor 85 mm. Constructed with a robust die-cast aluminum rotor assembly weighing 19 kg, the unit draws power from a variable supply of 138–350 V, ensuring adaptability across a range of inverter-driven systems. Its F-class Insulation Category and compact envelope make the 1MR200D-B085/S001 ideal for integration into automated machining centers and multi-axis turning equipment.

Operating at a Rated Speed of 6000 rpm, the rotor sustains top speeds up to 20000 rpm when supplied with a peak voltage of 201.9 V. The allowable ambient range of 0 to +40 °C and maximum installation altitude of 1000 m above sea level ensure stable performance in diverse factory and laboratory environments. To protect electronics and bearings, the rotor assembly requires a work fixture capable of supporting both the spindle and rotor mass at temperatures up to +200 °C, while its low protection rating mandates shielding from liquids and fine particulates. Flexible winding options (4B, 4C, 4D, 4E, 4F) enable customized torque and current profiles, with Rated Current 48–84 A and Rated Power 9–31 kW depending on the chosen configuration.

Maintenance and serviceability are simplified through a standardized mounting interface and clear specification of thermal limits and electrical characteristics. A 1-year replacement warranty from Bosch Rexroth Indramat underlines the manufacturer’s commitment to reliability and rapid support. Whether deployed in direct-drive main spindle motors or high-throughput automation rigs, the 1MR200D-B085/S001 delivers consistent high-speed operation with precision balance and minimal vibration.
