Series closing behavior

In motor technology , series connection behavior is a characteristic speed - torque behavior of certain electric motors . This behavior, which is also referred to as series connection character, occurs with DC series motors , single phase series motors , three phase series motors and repulsion motors .

Characteristic for series connection behavior

rotational speed

In the case of series connection behavior, the characteristic for the speed is that it is extremely load-dependent. The speed drops sharply with increasing load. At high torques, the speed is almost constant. When the load is reduced, the speed increases sharply. When the load is completely relieved, there is an extreme increase in speed. In the case of high-performance engines, this extreme increase in speed can increase to such an extent that it can go through and in extreme cases even be destroyed. In the case of smaller motors, the internal friction caused by the bearings and motor fan is usually large enough to prevent the motor from spinning. Because of the extreme load dependence, this speed behavior is also referred to as soft speed behavior.

Torque

The series connection behavior is characterized by a high starting torque. The starting torque is roughly three times the nominal torque .

The current consumption and the performance do not increase as much under load as with the shunt behavior .
