Tacho AT-402 (AT402, AT 402, at-402, at402, at 402)
Tachogenerators AT-402, 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 AT-402 two-phase asynchronous with the hollow rotor.
On the output shaft end of the terminal block is a stroboscopic disc.
Mount tachometer - Flanged with persistent rim.
Mode of operation - continuous.
