Elevator sensor

The special motor for the pump is a general machinery with a large amount and a wide range, and its annual power consumption accounts for 50-60% of the total power generation in the country, and more than 70% of the small and medium-sized asynchronous motors produced every year are used to drive the fan pump. For a long time, it is mainly used to adjust the valve to increase the resistance to achieve the purpose of regulating the flow. As a result, the throttling power consumption is very large. If the flow rate of the fan and the pump is adjusted by changing the speed of the drag motor, the system efficiency can be greatly improved and the cost can be saved.

Features:

1. This series of motors adopts a specially designed winding scheme.

2. The corresponding relationship between the power of this series of motors and the frame number is basically equivalent to that of Y series motors, that is, the high-speed gear of two-speed motors, most of which are equal to or close to the center height corresponding to the same power and speed of single-speed motors, which is convenient for users to choose and save energy.

3. The power setting of the motor is determined based on the load characteristics of the fan and pump, that is, the torque is proportional to the square of the speed, and the required power is proportional to the cube of the speed.

4. Because this series of motors is made of the motor itself winding to change the wiring to achieve the purpose of changing the speed, there is no need for a complex control system, and the one-time investment is very low and almost no special maintenance is required to operate reliably.

5. The appearance and installation size of this series of motors are the same as those of Y series single-speed three-phase asynchronous motors.
