Product Description:

The SD-B3.068 030-00 000 permanent-field servomotor by Bosch Rexroth has a keyway and a featherkey as per DIN 6885 specifications. This product is recommended to be used for less stringent requirements. The device has no special variation. This unit has a type label attached to its housing. It can be mounted in IM B5 and IM V3 mounting orientations. This motor has a vibration quality level of N according to DIN ISO 2373 specifications.

The product is cooled by either natural convection or thermal radiation. This device encompasses ball bearings on the flange end. The unit portrays a voltage constant of 134 V/1000/rpm. It must be ensured that the motor-inverter combination is based on a matched motor current and inverter current. This motor can withstand an axial force of up to 110 N with the IM V3 mounting style. The product cannot be mounted in IM V1 mounting orientation.

This device is balanced with a featherkey. The unit should not be knocked or hammered at the shaft extension as this can damage the rotor and ball bearings. Its braking resistor is designed to stop the motor in the shortest possible time with the maximum current. This servomotor is compatible with a Siemens 3TH short circuit braking contactor. The product related tacho cable cannot be used for trailing cable operation. This device needs a complete replacement of the tacho board when it encounters a fault. The unit is equipped with a flange of 116 mm size. It has no encoder or disk brake.
