Protection and Display Functions High Torque Brushless Direct Drive AC Motors

Product Description

1.Miniaturization and simple construction.
2.Save energy by thoroughly reducing various losses and realizing high efficiency.
3.High starting capacity.
4.Because it is a two speed motor, it can run at low speed / high torque and at high speed / constant  torque when combined with special service valve.
5.The special service valve includes manual valve and continuous| variable valve.
6.It can withstand 24.5mpa continuous operation and has high reliability.
7.The pressure resistance of drain oil line can reach 1.0MPa with high pressure oil seal.

8.it is a small lightweight product based on improving the basic performance, sliding characteristics and lifetime required by low-speed high torque motor. It has a good design of radial piston, which can meets the requirement of high output torque within the speed range and high output torque at low speed. Multiple displacement motor can change the working stroke 
of piston by changing the eccentric distance of cam to achieve variable effect.
