Product Description:
The Bosch Rexroth SD-B6.480.020-00.000 permanent-field servomotor has permanent magnets in its rotor. The device supports electronic commutation. There is a tacho and commutation sensor integrated into the unit’s windings. The rated torque of the product is 48 Nm. The mass of the device is 115 kg. The motor is 555 mm long. The unit has a speed of 2000 rpm. The length of the motor’s flange is 142 mm. The product is designed to be operated with a compatible inverter. The motor cannot be used alone. The maximum permissible operating temperature of the device is 40°C. If the unit is operated above the ambient temperature, its output reduces.
The SD motor is designed specifically for industrial applications. It is not intended to be used for residential purposes. The unit has a protection class of IP 54 as per DIN 040 050 / 40 053 specifications. The device is not equipped with a built-in encoder. The unit has a standard design and cannot be customized. Only the cables supplied by the manufacturer should be used to wire the motor. The installation, operation, and maintenance of the device should be performed only by fully trained and qualified personnel. The product documentation must be read carefully before handling the device.
The motor has ball bearings at its flange end. As the motor surface could be too hot to touch when it is live or immediately after it is turned off, a touch guard should be provided to avoid burns. Both the tacho and commutation sensors are brushless. The shaft extension of the motor should not be knocked or hammered because this might damage the rotor and ball bearings.
