Product Description

The SD-B3.050.030-01.000 permanent-field servomotor by Bosch Rexroth is not meant to be operated without a supporting inverter. This motor incorporates fixed ball bearings at the driving or flange end. The product can be used with an inverter that has a peak current rating of 5 A or 10 A. This device supports an axial force of up to 200 N at the shaft with IM B5 mounting style. The unit does not make use of any encoder to support its operation. It must feature adequate heat dissipation at the site of its installation. This motor is capable of maintaining the protection standard only if the minimum cable cross-sectional areas are observed in the cable glands.

The product is not balanced with any featherkey. This device should not be subject to knocking or hammering of its shaft as this can damage the rotor and the ball bearings. The unit supports the dismantling of only its tacho board in accordance with the instructions laid out by the manufacturer. It is necessary to check the motor-module combination using the type label before commencing the motor operation. This motor connection on the inverter side is done at the U2, V2, and W2 terminals.

The product depicts a connection cross-section of 1.5 mm2 in the mating connector. This device should not have any connection on pin 6 of its power connector. The unit incorporates a braking resistor of 5.6 Ohms and a minimum energy of 261 W. Its tacho cable has an admissible bending radius of more than 93 mm with one bending. This servomotor comprises a tacho board for conditioning its tacho as well as commutation signals.
