Further, described Connection Block includes integrated base plate and front shroud, and base plate is fixedlyed connected with the shell of motor body by bolt respectively with front shroud.
Further, the external splines of described replacing formula spline housing adapts to the internal spline shape of motor body rotating shaft and cooperates, and wherein external splines and internal spline are rectangular spline or are involute spline.
Further, the endoporus of described replacing formula spline housing and oil pump power shaft shape adapt to and cooperate, for the singly-bound axis hole or be internal splined hole.
Further, the outer wall of described motor body rotor is provided with several even spaced apart permanent magnet draw-in groove positions, and the opening both sides of each permanent magnet draw-in groove position are provided with the trip that prevents that permanent magnet from coming off.
Further, the other end of described motor body is provided with a cooling body.
Further, the other end of described motor body rotating shaft is provided with an encoder.
The utility model compared with prior art, its beneficial effect is:
1, the versatility height of the utility model and oil pump coupling, practical reliable, long service life and cost are low;
2, compact overall structure is reasonable, processing ease, and practicality is stronger, and economy is better.
