Product Description

The SD-B4.180.020-01.010 Bosch Rexroth permanent-field servomotor has a commutation sensor, a NTC thermostat, and a brushless tacho. This motor has separate power and tacho sockets. The product uses a tacho board for conditioning its commutation and tacho signals. This device related tacho board, connection cable, and inverter must be checked when a fault is encountered. The unit deploys either a plug connection or a solder connection for its tacho board. It has an overall length of 484 mm and a mass of 37.8 kg without the disk brake. This motor is intended to be handled by properly qualified personnel.

The product has an emf of 2.7 V/1000 rpm with a tolerance of +/-5% for its tacho. This device is prone to mechanical loading on its shaft when the operation takes place. The unit portrays a fixed ball bearing at its driving end. It may be needed to use a touch guard to handle the hot motor surface. This motor encounters damage to its rotor and ball bearings if the shaft extension is knocked or hammered. The product cannot be fitted with drive elements on its shaft. This device has two plug connectors on the housing for the inverter connection.

The servomotor has no connection on pin 6 of the socket for its power connection. This unit must be connected with the manufacturer's cables. Its tacho cable has a bending radius of more than 93 mm with one-time bending and more than 185 mm with repeated bending. The motor related tacho board must be repositioned correctly because of the fork-type light barriers when a replacement is made. The product can perform electronic commutation. This device is a major part of the manufacturer's Servodyn drive concept.
