A gear pump has a pump body, a pump cylinder connected with the pump body, a driving gear and a driven gear meshed with each other and disposed in the pump cylinder, and a rotor driving the driving gear through a driving shaft, and a sealing member. The pump cylinder is located between the pump body and the sealing member. The driving gear is mounted to or integrally formed with the driving shaft. The open end of the sealing member extends out of the outer housing and is sealingly connected with the pump cylinder so as to form a cavity, and the rotor and the driving gear mounted on the driving shaft are received in the cavity and have a coaxiality with the stator.

Gear pump

A gear pump has a pump body, a pump cylinder connected with the pump body, a driving gear and a driven gear meshed with each other and disposed in the pump cylinder, and a motor driving the driving gear through a driving shaft. The pump cylinder is located between the pump body and the motor. The driving gear is mounted to or integrally formed with the driving shaft. A first bearing and a second bearing are disposed on respectively sides of the driving gear, one end of driving shaft is received in the first bearing, and the other end of the driving shaft extends through the second bearing and into the motor and forms a shaft of the motor.

A small PMDC motor has a wound salient pole armature. The armaturehas a winding guidedisposed within each winding tunnelformed between adjacent salient poles of the armature. The winding guideis arranged to separate the radially inner portion of the respective winding tunnel whereby windingswound about the adjacent salient poles of the armature are restrained from entering into the opposite radially inner portion of the winding tunnel
