Tacho TG-4 (TG4, TG 4)
Tachogenerators TG-4, in asynchronous circuits automatic tachogenerators, serve as an information item, the output voltage is linearly dependent on the rotor speed at a constant phase shift between the excitation voltage Uin and the output voltage U out.
The device is an electric car with a hollow non-magnetic rotor.
Tacho TG-4 phase asynchronous with the hollow non-magnetic rotor.
On the stator has two windings: the excitation and the generator.
Mount tachometer - for housing and flange.
