Product Description:

Bosch Rexroth is famous for its advanced drive and control technologies which are used in different industries throughout the world. The MRS200A-A108-NN MRS Synchronous IndraDyn H Motor showcases the company's commitment to robust and reliable solutions. This model of the rotor has a frame size of 200 and is improved for integration with primary parts MLP200C and MLP200D.

The MRS200A-A108-NN Synchronous IndraDyn H motor is a secondary component of the motor that has a weight of approximately 30.6 kg per meter, which contributes to its durability. It is designed for high voltage applications. It functions effectively with up to 750 VDC and is fully compatible with Rexroth IndraDrive and HMS/HMD controllers for versatile use across various industrial applications. This rotor operates efficiently within an ambient temperature range of 0 °C to +40 °C and is suited for installations at elevations from sea level to 1000 meters. If operating conditions exceed these limits adjustments to rated values such as torque and speed are required based on specific correction factors. This rotor of synchronous IndraDyn H motor adheres to climatic class 3K4 as per DIN EN 60721-3-3 and shows its capability to withstand a relative humidity range from 5% to 95% and an absolute humidity of 1 to 29 g/m³.

The MRS200A-A108-NN Synchronous IndraDyn H motor handles temperature changes at a maximum rate of 0.5 °C per minute which is crucial for the environment. The rotor employs either water or a water-antifreeze mixture for cooling and maintains coolant inlet temperatures between +10 °C and +40 °C with a minimum flow rate of 4 liters per minute and a maximum operating pressure of 5 bar at the coolant inlet.
