For order is possible effectively delivery of any quantity.
AD-25A electric motor (AD25A, BP 25 A, AD-25-A, BP 25A, AD25-A, AD25 A)
 
The motor AD-25A 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.
