    Abstract: A permanent magnet motor and a power tool are provided. The permanent magnet motor includes an excition and an armature. One of the excition and armature comprises a first magnetic core with permanent magnet members embedded therein. The permanent magnet members are arranged along a circumferential direction of the first magnetic core, such that an inner circumferential surface of the first magnetic core forms a plurality of magnetic poles with alternative polarities. The other of the excition and armature comprises a second magnetic core and windings. The second magnetic core is received in the first magnetic core and comprises teeth with the windings wound therearound. The embedded construction prevents the permanent magnet members from becoming disengaged from the magnetic core. A stronger magnetic pole can be formed by mutual induction of the permanent magnet members and the magnetic core, which increases the power density of the motor.

    Abstract: A permanent magnet rotor includes a shaft, a rotor core fixed to the shaft, and multiple magnet sets. The rotor core has multiple groove sets for receiving the magnet sets. Each groove set has two grooves spaced apart by a first section of the rotor core. The first section has a width gradually decreasing from a radially inner end to a radially outer end. Each groove has a width gradually increasing from a radially inner end to a radially outer end. Each magnet set includes two magnets respectively received in the grooves of a respective groove set. The magnets of a magnet set are magnetized in a same direction, and every two adjacent magnet sets are magnetized in contrary directions creating multiple magnetic poles. The number of magnetic poles is equal to the number of magnet sets.

    Abstract: A medical pump includes a single phase synchronous motor, a rod piston, a cylinder for receiving the rod piston for reciprocating motion therein. The single phase synchronous motor includes a stator and a rotor rotatable relative to the stator. The rotor includes a plurality of permanent magnets. The stator comprises a stator core and a winding wound around the stator core. The stator core comprises two opposed pole portions that define there between a rotor receiving space for receiving the permanent magnets. The medical pump has a compact structure. In addition, the motor of the medical pump has a constant rotation speed and has a smaller size and less weight under the same output power conditions as traditional motors used in medical pumps. The medical pump is particularly suitable for use in atomizers.

    Abstract: A solenoid includes a stationary member, a movable member being movable relative to the stationary member and spring disposed between the stationary member and the movable member. The stationary member includes a housing with an end wall and a side wall, a first permanent magnet attached to the end wall, a second permanent magnet attached to the side wall and a magnetic flux concentrator configured to concentrate a magnetic field generated by the second permanent magnet with a magnetic field generated by the first permanent magnet. The movable member includes a head inserted into the housing. The head is made of magnetically conductive material. The stationary member further includes a coil surrounding the head of the movable member. When the coil receives a pulse current, the movable member is driven from an extended/retracted position to a retracted/extended position.
