AT-2

For order is possible effectively delivery of any quantity.
Tacho AT-2 (AT2, AT 2, at-2, at2, at 2)
 
Tachogenerators AT-2, 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-2 single-phase asynchronous with the hollow non-magnetic rotor.
On the stator has two windings: the excitation and the generator.
Mount tachometer - flanged.
Mode of operation - continuous.
