Radiotone Variable Autotransformer with Built in DC Motor

This is a very compact Motorized Variable Autotransformer (colloquially known as Variac) which uses the coil cavity to fit the motor assembly. We use roller brushes in this product for low torque and smooth operation. The speed of the motor can also be varied (time span for one rotation) by varying the DC voltage.
