1 speed energy saving

Permanent magnet speed control technology to replace the original system to control the flow or pressure of the valve or damper baffle, by adjusting the permanent magnet rotor and rotor rotor meshing area to achieve the fans, pumps and other centrifugal load speed, to achieve the flow or pressure Of the continuous control, to meet the technical requirements at the same time the purpose of economic operation. Compared with the throttling adjustment method of the valve, the speed regulation method of permanent magnetic governor can save 10% ~ 60%.

2 small vibration

Permanent magnetic governor replaced the original rigid coupling, the use of air-gap magnetic field transmission torque, the motor and the load is not mechanical connection, so that the load side of the vibration will not be transmitted to the motor side, the motor side of the vibration will not pass To the load side. Permanent magnet governor also cut off the vibration in the transmission of the amplification effect, so you can eliminate the rigid coupling vibration amplification effect, reducing system vibration. At the same time, permanent magnet governor can also reduce the vibration due to large errors in the center. According to the measured data of permanent magnet speed controller in practical application, the vibration of the motor after the modification can be reduced by 50 to 85%.

3 low noise

Permanent magnet governor without mechanical transmission of torque, the noise on the environment is not large. Especially for air-cooled equipment, our company carried out a large number of experiments on the heat sink angle to find the best fin angle to meet the cooling requirements while reducing noise. Measured at 1 meter next to the permanent magnet governor, the noise is generally below 80dB, with ordinary shield can be, do not need to add muffler cover.

4 high reliability

Permanent magnet governor is mainly composed of three components, of which the rotor and permanent magnet rotor rotor is a purely mechanical components, the structure is simple, the failure rate is almost zero, stable performance. The high reliability of the device means the following:
(1) Permanent magnet governor life of 25 to 30 years, long depreciation period, long-term use of small investment;
(2) Permanent magnetic governor mean time to failure, the low frequency of maintenance and repair requirements, low maintenance and repair costs, bearing grease added every 2000h, bearing replacement every 3 years, seals and other wearing parts.

5 light load start and overload protection

When the motor starts with load, the current momentarily rises, which is usually 4 ~ 7 times of the rated current, and lasts long, impacting the power grid. Permanent magnet governor with light load start function, first start the motor, and then add the load, the starting current peak motor rated current for 4 to 7 times, but the duration is very short, reducing the motor thermal shock load and On the power grid, thereby extending the working life of the motor, but also effectively reduce the impact of the load on the start-up transmission system, but also reduce the impact of the transmission system itself to start to extend the use of key components such as bearings and seals Life expectancy, to ensure the safe and reliable operation of equipment, reduce the motor starting and braking the impact of the motor and load. Motor and load can be selectively activated and stopped, extending the life of the motor, load and switch, improve the system start-stop performance.

Permanent magnet governor for impact load also has a buffer through the slip and automatic protection function, making the system greatly reduce the failure. Permanent magnet governor can also achieve overload protection: As there is no mechanical connection between the motor and the load, when the load is overloaded or stalling, the permanent magnet governor can automatically disconnect the torque transfer from the motor to the load, at this time The motor runs at no-load and the load stalls, which can completely eliminate system damage and huge losses caused by overload, prolong the service life of the motor and load, and improve the reliability of the entire motor drive system.
