YWCM series high-power specially used in oilfield energy-saving permanent magnet brushless pumping unit electromotor and its control system

Brief introduction:
YWCM pumping unit dedicated permanent magnet brushless direct current motor is a new style energy-saving electromotor which is designed especially for the operation condition of current
oilfield pumping unit, the operation should be more reasonable and energy-saving after using
this electromotor in pumping unit, it can realize comprehensive energy-saving 10%—40% if

Replace present Y series triphase asynchronous motor, also can be used widely in oil, chemical industry, aviation, machinery, etc.

Function feature:
1.High operating efficiency: the performance of permanent magnet brushless direct current motor is synchronous working, rotor speed and stator rotating magnetic field completely synchro Compare to asynchronous motor, no slipping damage; compare to ordinary synchro motor, the rotor no need more excitation power, so eliminate the excitation loss.Therefore, the rated efficiency of permanent magnet brushless direct current motor can be to 94% above and exceed about 6-7 percentage point compare to ordinary asynchronous motor.

2,High voltage-ampere efficiency: by optimization design when underloading in certain scope the efficiency is higher than rated value, it can be about 96% at the most, and the peak efficiency area is Just right in the average loading area of the motor, so that the high efficiency area can be Extended, greatly improve the average operating efficiency in the whole stroke. While when in Underloading the efficiency of asynchronous motor have been lower than its rated value far, the two average efficiency difference be to more than 10% in the whole loading range of variation And because of most of the pumping unit working time is in the underloading condition, the average worked energy-saving rate can be higher, and the saving efficiency can be more ideal.
