This series of motors operate in a constant torque speed regulation mode within the frequency range of 5-50Hz, running smoothly without any torque pulsation. They also have a relatively high starting current and can output constant power characteristics within the frequency range of 5-50Hz. In addition, the power rating, installation size, and base center height of this series of motors comply with the international IEC standards. Their corresponding relationships are consistent with those of the Y2 series three-phase asynchronous motors, and the interchangeability is highly versatile. This series of motors have a cage structure, are reliable in operation, and are easy to maintain. They are also equipped with an independent cooling fan to ensure good cooling performance at different rotational speeds.
The speed control system composed of this series of motors and the SPWM frequency conversion device has several advantages compared to other speed control methods, including significant energy-saving effect, excellent speed control performance, wide speed regulation range, excellent rapid response capability, wide application scope, and high performance-price ratio. It is one of the most advanced systems in the current AC speed control schemes. It can be widely used in the main shaft transmission of CNC machine tools, textile, chemical, metallurgical industries for constant torque and constant power speed control, as well as in energy-saving speed control of fans, pumps, etc. It also has a computer control interface, which helps to achieve the automatic control of the speed control system. It is a high-tech energy-saving product currently promoted by the state.
