Product Description:
The SD-B4.140.020-00.000 permanent-field servomotor by Bosch Rexroth has a commutation sensor and a brushless tacho. This motor also comprises a terminal block in its top right corner. The product is highly resistant to demagnetization. This device portrays a special magnet configuration. The unit experiences a change in its fit characteristics because of continuous loading with alternating torques. It faces multi-directional tension under load because of factors such as radial and axial forces, flexural torque, and torsion. This motor is not fitted with a disk brake by the manufacturer. The product installation must be done by taking care to ensure that there is adequate heat dissipation.
This device has a voltage constant of 206 V/1000/rpm at 40 °C ambient operating temperature. The unit must be associated with only an inverter that matches in terms of motor current and inverter current. It withstands a maximum of 200 N axial force with IM B5 mounting style. This motor incorporates a temperature monitoring function using a NTC thermostat. The product supports a dismantling action to be carried out only for its tacho board. This device also allows its connection sockets to be replaced if there is a need to do so. The unit may get damaged if it is connected to an unapproved or inappropriate inverter. It is necessary to check the motor-module combination using the type label before commencing the initial operation of the motor.
This motor has live terminals when its rotor is driven as a result of the permanent magnet excitation. The product encompasses short circuit braking resistors with a resistance of 3.3 Ohms and a minimum energy of 293 W. This device is meant to be connected with only cables approved by the manufacturer. The unit needs a replacement of the entire tacho board to be done if it has encountered any fault. Its tacho cable must not exceed 100 m in length. This servomotor needs sealing to be done on pin 12 of its tacho connector using the provided blanking plug.
