MV1028 DC Machine

Description

Machine Test System

A DC-machine is used together with test machines, e. g. a synchronous machine as below in order to study characteristics. The DC-machine is placed on a machine bed on which different test machines can be mounted quickly and simply. The DC- machine can be connected either as brake generator or driving motor depending on the object to be tested. The connections are made as safety terminals on the panel, integrated with the machine. The machines have an anodized aluminium foundation, coupling, eyebolt and terminal block with mimic diagram. Guides and plastic rails under the foundation ensure that each machine is aligned accurately and slides easily on the stand.

MV1028 DC Machine

Complete with interpoles. This machine is used in test machine sets such as motors or generators, mounted on a 10 mm thick anodized aluminium plate to be placed on the machine bed MV 1004.
