Product Description

The SD-B4.140.030-04.000 permanent-field servomotor by Bosch Rexroth must be operated only with an inverter that has been approved by the manufacturer. This motor must be disconnected from its power supply before any connection is done to it. The product is equipped with a disk brake and a shat with a keyway and a featherkey. This device related mating connectors have to be bought separately. The unit features the integration of a brushless tacho and a commutation sensor. It is necessary to compare the motor-inverter combination using the type label before the initial operation. This motor is associated with a large overload capacity.

The product depicts its power loss in the windings present in the stator. This device has a peak current rating of 45.5 A at an ambient temperature of 20 °C. The unit is an integral part of the manufacturer's Servodyn drive concept. It can be used for any mechanical engineering associated application. This motor is not designed to be deployed for residential use. The product is cooled by natural convection as well as thermal radiation. This device is highly resistant to demagnetization.

The servomotor has an IP 54 protection rating because of its completely sealed construction. This product comprises a brushless tacho plus a commutation sensor for velocity feedback or detecting the position of the rotor. The device associated feed axis has no play in standstill mode because of the disk brake. This unit has no second shaft end. Its type plate must be visible at the time of installation. The motor portrays a maximum theoretical acceleration of 9900 rad/s2.
