For order is possible effectively delivery of any quantity.
The motor-tacho ADT-331 (ADT331, ADT 331)
 
The motor-tacho ADT-331 is designed for automatic systems, such as low-power drive transformer for remote transmission angle with selsyns and rotary 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-331 is the same engine with an optional built-in induction tachometer, whose signal can be used for speed feedback in the control circuit.
