Product Description

The Bosch Rexroth SD-B4.140.020-04.000 permanent-field servomotor has a backlash-free disk brake. This motor can be mounted either vertically with the shaft facing upward or horizontally. The product may be very hot during and soon after its operation. This device should at no time be dismantled. The unit is used with an inverter for any mechanical engineering related applications. Its braking resistors have a resistance of 3.3 Ohms. This motor is brought to a stop by the braking resistors in minimum time with the maximum current when an emergency stop situation is triggered.

This product needs to be inspected for the proper functioning of the disk brake after 1000 emergency-stop braking situations. The device weighs 37.8 kg without the disk brake. This unit features its brake connection as a part of the power connection. It must always be matched with the right and appropriate inverter. This motor encounters mechanical load on the shaft when it is being operated.

The product has no temperature-related expansion of the driving side because of its fixed bearing. This device has live terminals when its rotor is being driven because of permanent magnet excitation. The unit is connected to the inverter through two plug connectors on the motor and three terminals on the inverter. Its braking resistors have a minimum energy of 293 W. This servomotor associated disk brake can be operated only when the axis is in stationary mode. The product achieves a rotational speed of 0 rpm when the SW1 setpoint has no voltage. This device supports a length of up to 100 m for the tacho cable. The unit portrays either solder connection or plug connection for the tacho board.
