Abstract
The utility model relates to a flow valve direct-driven by a taper permanent magnet synchronous motor. The flow valve is formed by connection between the taper permanent magnet synchronous motor and a valve via a bolt. A motor rear end cover of the taper permanent magnet synchronous motor is externally connected with a fan brake wheel, on which a brake ring is fixed. The fan brake wheel is fixedly connected with a rotor via a locking nut. A valve core is connected with an output shaft of the rotor via a nut and performs rectilinear motion in a valve body. After a winding of a stator is electrified, the rotor performs upward motion by the effect of an axial magnetic pulling force to promote the brake ring of the fan brake wheel to be separated from the motor rear end cover. The motor is capable of driving the nut to rotate and driving the valve core to perform reciprocating motion, thus achieving flow adjustment. When the valve core is adjusted to a preset position, a power supply for the winding of the stator is disconnected and the inherent axial magnetic pulling force of the permanent magnet synchronous motor is overcome by compression springs to push downward movement of the rotor and the brake ring of the fan brake wheel is pressed tightly on the motor rear end cover, which achieving rotator brake and keeping the position of the valve core fixed so as to reduce losses.
