The Bosch Rexroth Indramat SD-B4.140.020.01.000 is a durable permanent-field servomotor with a nominal speed of 2000 rpm, featuring two mating connectors for inverter connection. This brushless unit provides velocity feedback through a tacho and requires specific inverters for optimal operation. It is designed for vertical IM V3 mounting and withstands radial and axial mechanical loads. With a high protection standard, it resists demagnetization and offers substantial overload capacity. The motor includes Class F insulation under DIN VDE 0530 standards and a NTC thermostat with a -10 °C to 145 °C operating range. Its robust construction ensures splash protection and a minimum of 20,000 operational hours. Proper handling precautions, such as wearing gloves or using a touch guard, are necessary due to heat risk. The unit's technical details are displayed on its type label, and disconnection from power is essential before repairs to prevent rotor or bearing damage.
