  • Patent number: 10451023
    Abstract: An engine, an engine starter and its housing assembly are provided. The housing assembly includes a gear mounting portion for mounting a driving gear and a switch mounting portion for mounting a solenoid switch. The switch mounting portion comprises a connecting portion and a cover body. The connecting portion is connected with the gear mounting portion and comprises a through structure for mounting the solenoid switch, the cover body covers a top end of the through structure. A wall of the connecting portion corresponding to the gear mounting portion defines an opening for mounting a shifting fork, which is in communication with the through structure.

  • Patent number: 10199886
    Abstract: A single phase brushless motor and a power tool are provided. The single phase brushless motor includes a stator and a rotor. The stator includes a stator core and windings wound around the stator core. The stator core includes a yoke and at least two teeth. The tooth includes a tooth body and a tooth tip. The tooth tip includes first and second pole shoes. The two pole shoes of each tooth are symmetrical about a center line of the tooth body. Each tooth defines a positioning groove facing the rotor between the two pole shoes. Pole shoes of adjacent two of the at least two teeth are spaced apart by a slot opening. A width of the positioning groove is greater than a width of the slot opening. The peak value of the cogging torque of the motor is increased, and the motor has a large startup torque.

  • Publication number: 20160344244
    Abstract: A single phase brushless motor and an electric apparatus are provided. The motor includes a stator and a rotor. The stator includes a stator core and windings. The stator core includes a yoke and at least two teeth. The tooth includes a tooth body and a tooth tip. The tooth tip includes first and second pole shoes. The rotor is received in a space defined between the first pole shoes and the second pole shoes. Each tooth forms a positioning groove facing the rotor between the first pole shoe and the second pole shoe. The first and second pole shoes are symmetrical about a central line of the tooth body and the positioning groove deviates toward the first pole shoe, such that the rotor startup capability in one direction is greater than the rotor startup capability in an opposite direction. The single phase motor has a larger startup torque with enhanced startup capability.

  • Patent number: 8919511
    Abstract: A starter motor includes an electric motor, a drive shaft driven by the motor and an inertia drive pinion which includes a driver in threaded engagement with the drive shaft, a pinion shaft rotatably sleeved on the drive shaft, an output pinion being able to rotate with the pinion shaft, and a one way clutch. At least one elastic member is arranged between the output pinion and the pinion shaft in the axial direction to resiliently support the output pinion to move along the pinion shaft. A one way clutch especially suitable for the starter motor was also disclosed.
