Tacho DIG-3 (DIG3, DIG 3)
Tachogenerators DIG-3, 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 DIG-3-phase asynchronous with the hollow non-magnetic rotor.
On the output shaft end of the terminal block is a stroboscopic disc.
