Product Description

The Bosch Rexroth SD-B4.140.020-41.000 permanent-field servomotor is a high-performance motor that is designed exclusively for industrial use. This motor can be used for all kinds of mechanical engineering related applications. The product encompasses permanent magnets embedded in its rotor. This device has a constant throughout the speed-torque characteristic range. The unit has a vibration quality level N as per DIN ISO 2373 specifications. The unit has a power plug and a tacho plug with plastic protective caps as its mating connectors. It has a type label with key technical details fitted onto the housing.

This motor is equipped with fixed ball bearings at its driving or flange end.

The product must be disconnected from the power supply before its installation is done. This device has live leads when it is in use due to permanent magnet excitation. The unit has an electrical time constant of 11 ms at 20 °C. It must be ensured that the minimum cable cross-sectional areas are observed in the cable gland so that the protection standard is maintained. This servomotor is cooled by either thermal radiation or natural convection. The product tends to portray restricted operation if it is connected to an unapproved inverter.
