Product Description

The Bosch Rexroth SD-B5.250.020.10.000 is a reliable permanent-field servomotor with permanent magnets in its rotor. The device has a brushless tacho and commutation sensors. The motor can be operated with a TC inverter for mechanical engineering related applications in industrial environments. There is a rating plate attached to the housing of the product for identification and to know the technical details. The maximum noise rating of the unit at a distance of 1 meter is 64 dB (A). When installing the motor, the user must ensure sufficient heat dissipation.

The SD motor meets a high protection standard because of its completely sealed construction. The temperature monitoring of the motor is evaluated in the inverter. The protection standard of the unit is IP 54. For the device to function, at least one supply module is required. The connection between the inverter and the unit is done on the motor side via plug-in connectors. The shaft of the product does not have a keyway or feather key. The motor has vibration class level N. The torque of the motor is 25 Nm. The nominal speed of the device is 2000 rpm. The current rating of the unit in standstill mode is 17.2 A.

The servomotor weighs 58.6 kg and its length is 489 mm. The device has a thermal time constant of 260 minutes. The device is cooled by thermal radiation and natural convection. The operation of the product will be restricted if it is connected to an inverter that the manufacturer has not approved. The tacho of the unit is meant for velocity feedback. It should be noted that, as high surface temperatures could occur on the housing of the device, a touch guard should be provided if necessary.
