YSPA series variable frequency speed control three asynchronous electric
YSPA series variable frequency speed regulation three asynchronous motors are three asynchronous motors with frequency conversion and speed regulation based on frequency conversion speed regulating device. They belong to electromechanical integration products.
YSPA series motor has high efficiency, wide speed range, high precision, stable operation, easy operation and maintenance. The installation size accords with the International Electrotechnical Association (IEC) standard. The protection grade of the shell is IP44, and the quota is a continuous quota based on the continuous working system (S1). The basic series of YSPA series motors is 4 stages. The rated voltage is 380V and the rated power is 50HZ. It can run continuously in the range of 5 67HZ and 5 50HZ for constant torque operation, and 50 67HZ runs for constant power. 3KW and the following "Y" connection, 4KW and above for the "delta" connection. 0.55 - 55KW is B - class insulation and 75 - 200KW is F - grade insulation. YSPA series motors are suitable for all kinds of mechanical equipment that require continuous speed regulation, such as rolling steel, printing and dyeing, paper making, chemical industry, textile, pharmacy and so on.
The YSPA series motor has three basic structures and installation types.
B3: structure frame with feet, endshield without flange.
B5: frame without foot, end cover structure with more than the base flange.
B35: frame with foot, structure of the end cover with flange is larger than the base.
