(for order is possible effectively delivery of any quantity)
Tacho AT-161 (AT161, AT 161, at-161, at161, at 161)
Tachogenerators AT-161, 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-161 single-phase asynchronous with the hollow non-magnetic rotor.
On the output shaft end of the terminal block is a stroboscopic disc.
Mount tachometer - in the case.
