MV1007-405 DC-Machine


Test Machines

The characteristics and data of Terco electrical machines are similar to those of larger machines.

The Terco test machines have a robust construction with more iron and copper than normal to enable overloading.

Approximately 20 % overload is possible for a maximum duration of 10 minutes without damaging the machines.

Terco machines boost higher saturation limits than machines with less iron.

Please pay attention to the weight of Terco machines in comparison with other suppliers machines.

The weight will give you an indication of how much iron and copper the machines have compared to other producers of the same power (ca 1kW).

The test machines have a foundation providing accurate alignment laterally and an accurate shaft height of 162 mm.

Guides and plastic rails below the foundation simplify alignment and enable good positioning maneuverability on the machine bed. Special clamps are used to secure the machines to the machine bed. Connection is made via 4 mm safety terminal sockets mounted on a terminal panel showing the internal connections of the machine. Other voltages than those shown can be arranged on request.
