For order is possible effectively delivery of any quantity.
The motor-tacho ADT-25 (ADT25, ADT 25)
The motor-tacho ADT-25 is designed for automatic systems, such as low-power drive transformer for remote transmission angle with selsyns and rotating transformers.
Designed as a two-phase induction motor with a hollow rotor bezobmotochnym.
One of the phases is the field winding, the second - the control winding, which signal that sets the direction and speed.
The motor-tacho ADT-25 is the same engine with an optional built-in induction tachometer, a signal which can be used for speed feedback in the control circuit.
