MODULATED STATOR WINDINGS OF THE MOTOR FOR FAN DRIVES
DescriptionIn poultry industry, animal breeding, greenhouses and vegetable stores a significant amount of fans with asynchronous motors is used to create a microclimate. The fan speed of the fan should be regulated in order to improve the efficiency, so the multispeed motors are used for the fan drives. Line produced two-speed motors with a proportion of the poles number 1:2 have a polar-switched Dahlander stator winding. Two-speed motors with a proportion of the poles number 3:2 and 4:3 have only one stator winding which is poleswitched by the method of amplitude phase shift keying. A drawback of the windings is that they have different energy indicators at different spin rates. In order to create rational diagrams with switching according to the number of poles, which is multiple of three, it is proposed to implement a polyphase MMF modulation of the three-phase winding. As a result of the study, there were procured the stator windings at 4 and 6 poles, which enabled to change the spin speed of the motor in the fan drives without breaking the drive power circuit by the scheme Δ / ΥΥ
