Product Description

The Bosch Rexroth SD-B5 250.015-10.000 is a versatile permanent-field servomotor. The motor works with an inverter in a Servodyn drive system. The inverter should be from the same manufacturer. The unit is not equipped with a built-in encoder. The ambient operating temperature of the motor is 0 to 40°C. The product can be mounted in horizontal and vertical positions. It can be mounted vertically only in the case of the IM V3 orientation. In this case, care should be taken to ensure that no fluid is collected at the flange end plate. The motor has ball bearings at the flange end. The minimum service life of the ball bearings is 20,000 operating hours.

The SD motor is cooled by natural convection and thermal radiation. The device should be installed in such a way that there is adequate heat dissipation. There could be high surface temperatures on the unit. If necessary, a touch guard should be provided. There is a tacho and a commutation sensor integrated into the motor’s non-driving end. Both the sensors are brushless. The torque constant of the motor is 1.94 Nm/A. Its winding resistance is 1.26 Ohm, and its winding inductance is 26.8 mH.

The drive elements, such as the clutch disks, belt pulleys, and gear wheels must be fitted and removed using a suitable extraction and mounting device. The thread on the shaft extension can be used. It should be noted that the shaft extension on the motor should never be hammered or knocked because this can damage the rotor and the ball bearings. The product has high resistance against demagnetization as its admissible peak torque is three times the rated torque.
