MS series motors is designed in control modules, can combine
freely .
The core of MS series is composed by stator, rotor, and
roller piston distributors, it is hydraulic function manifold.
Drawing 2 is sketch map for stator and rotor structure
( 8 piston 6 action hydraulic motor model), 6 action is
means piston roller works 6 times per circle, action time
is stator roller path concavo-convex time. Interior curve
is component of umpty curve section, each curve section
is make up of uplifted section, transitional section and
degressive section, roller past the curve section one
time, piston moved one time. Different curve section caused
piston located in different cavities .
Drawing 3 is sketch map for piston-roller pressured.,
when piston moved to uplifted section and connected with
high-pressure oil, Hydraulic force Fy will moved around
axis direction, this force of stator and rotor caused
Fn force, Fn can be divide into Ft and Fr, Fr will balance
Fy and Ft will moved to motor casting which caused motor
axis torque move to transitional section and degressive
section, in this way rotor down with stator curve, bottom
of piston will connected with oil casting then hydraulic
oil be returned to oil casing, it is caused optimized
curve, high torque and high inverted energy efficiency.
If MS motor used in closed system, the compensation pressure
range will be 1.2-3pa. If it is in open system, the backpressure
is system backpressure. In order to ensure rotor can not
renegaded stator, it required oil casting keep backpressure,
more backpressure high speed, this speed base on without
any noise when rotor moved.
