Tacho AT-503 (AT503, AT 503, at-503, at503, at 503)
Tachogenerators AT-503, 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 AT-503 single-phase asynchronous with the hollow non-magnetic rotor.
On the output shaft end of the terminal block is a stroboscopic disc.
Mount tachometer - flanged.
Mode of operation - continuous.
