DC Motors, Linear actuators and Solenoids

Transmotec offers a vast range off push and pull type solenoids in various configurations and sizes. All our solenoids are in standard delivered with spring for return movement of the plunger. Solenoids are commonly used in applications needing a cost effective electric control of a two position fast mechanical movement. Solenoids are not suitable for positioning drive or with feedback loops.

Solenoids are electromechanical components consisting of a wounded coil that are shaped around a freely moving steel or iron plunger. When the solenoid is connected to a voltage the current will generate a magnetic field which will apply a force on the plunger. The force direction will point to the centre of the solenoid.

The solenoids plunger force is a linear function of the current through the coil but is also strongly depending on the distance of the center of the plunger and the center of the solenoids.

A common method in operating solenoids is to apply it to a higher voltage in relation to its nominal voltage. The solenoids nominal voltage is the voltage upon which the solenoids can be applied continuously with out being over heated. By applying a higher voltage to the solenoids the force will also become higher but the operation time should be less than one minute depending on the voltage level and the duty cycle of the operation.
