Product Description

The SD-B4.140.020-10.000 permanent-field servomotor from Bosch Rexroth and a supporting inverter in unison drive the manufacturer's Servodyn system. This motor comes integrated with a brushless tacho plus a commutation sensor. The product is designed for use in applications with velocity and position servo loops. This device has a shaft that does not feature a keyway and featherkey. The unit uses the same socket for power and brake connection. It has N vibration quality level. This motor has no special customization.

The product comes with a temperature monitoring function evaluated by the inverter. This device must have no fluid collection at the flange. The unit uses two mating connectors for its electrical connectors. Its tacho board must be replaced completely when it has a fault. This motor is characterized by a cylindrical shaft extension according to DIN 748 specifications. The product cannot be fitted with drive elements on the shaft as the shaft extension has no threads.

This device has a wide ambient operating temperature range of 0 °C to 40 °C. The unit portrays a maximum noise rating of 64 dBA at a distance of 1 m. Its bearings have a lifespan of at least 20,000 operating hours as per ISO 281 specifications. The servomotor is associated with a large overload capacity. This product uses the commutation sensor to maintain control over the commutation of the phase currents in the inverter. The device portrays a voltage constant of 206 V/1000/rpm at 40 °C. This unit must be used with an inverter that is matched in terms of motor and inverter currents.
