<p>A permanent magnet direct drive mud pump (100) has a permanent magnet motor (40), a shaft (41) connected to the permanent magnet motor, and a pump head (49) connected to the end of the shaft opposite the permanent magnet motor. The permanent magnet motor (40) has a housing (42), a stator (62) positioned within the housing, and a rotor (64) cooperative with the stator and positioned interior of the stator within the housing. The rotor (64) is interconnectable with the shaft so that the rotational motion created by the permanent magnet motor (40) can be directly imparted to the shaft and, accordingly, to the pump head without the use of a transmission.</p> |
