Dynamic analysis and synthesis of mechanisms

with consideration of mechanical characteristics

of asynchronous electric moto

Bauman Moscow State Technical University, Moscow, 105005, Russia

The correct choice of drive parameters is a prerequisite for high-performance and eco-

nomical operation of the machine set. Dynamic synthesis of electrically powered ma-

chines usually accounts only for mass and size of a flywheel which provides the given

non-uniformity of movement, and the parameters characterizing the operation of the mo-

tor are not considered. This approach does not allow effective use of electrical energy.

The article presents a method of dynamic analysis and synthesis of a machine set with an

asynchronous electric motor, which makes it possible to explore not only the non-

uniformity of movement, but also the parameters that characterize the operation of the

motor: the efficiency and power factor. This technique is based on the l-section motor

equivalent circuit. When conducting the dynamic synthesis of electric drive we propose to

determine not only the moment of inertia of rotating mass, but also the gear ratio of the

transmission mechanism according to the conditions to maximize the engine efficiency

and the possibility to start the drive. We used the proposed method in dynamic analysis

and synthesis of a plunger pump.

Keywords:

electric drive, equivalent circuit, dynamic analysis, efficiency factor, power

factor
