Product Description

The Bosch Rexroth SD-B6.480.020-15.000 is a high-performing permanent-field servomotor in the SD series. The motor has a nominal speed of 2000 rpm. The motor is designed for inverter operation. It supports electronic commutation. The rotor of the device contains permanent magnets made of ferrite. The unit has a protection class of IP 54 according to DIN 040 050 / 40 053 specifications. The ambient temperature at which the product can be operated is from 0 to 40°C. The motor has ball bearings at its driving end where the flange is located. The device has an insulating material class of F as per VDE 0530. At the time of installation, the user should ensure sufficient heat dissipation.

The SD motor has brushless tacho and commutation sensors integrated into the non-driving end. The elements of the drive, including belt pulleys, gear wheels, and clutch disks, should be fitted and removed only using appropriate mounting and extraction devices. The user can use the thread on the shaft extension. It must be noted that the shaft extension should not be knocked or hammered because this would damage the motor’s ball bearings and rotor. The weight of the device is 115 kg. The current rating of the unit in standstill mode is 32.4 A. Its peak current at 20°C is 129.6 A.

For the SD motor to function, at least one supply module is required. The connection between the motor and the inverter is performed on the motor side via plug-in connectors. The device delivers reduced output when its permissible operating temperature range is exceeded. The NTC thermistor present in the windings of the motor protects it against thermal overload.
