摘要： It is necessary to keep the positional relation between a stator and a housing for a long time, so the stator and housing must be fixed to each other with increased adhesive strength. Since this kind of rotary electric machine is a mass-produced product, the fixing method is demanded to be simple enough to be suitable for mass production. In order to meet this demand, in a rotary electric machine, for bonding and fixing the stator and the housing for covering the stator by synthetic resin, a plurality of projecting parts are formed on the inner circumference of the housing and synthetic resin is poured into between the stator and housing to bond and fix the stator and housing.

摘要： An outer rotor type hybrid stepping motor includes a stator, a rotor, a magnet disposed axially in the stator or the rotor, a stator core disposed inwardly from a gap between the stator and rotor, and a stator winding on the stator core. The rotor is disposed outside the gap. The magnet has an axial cross sectional area A. The residual magnetic flux density of the magnet is Br, and a total of magnetic fluxes exiting axially from the surface is A×Br. A gap average magnetic flux density, determined by dividing A×Br by the top cross sectional area small teeth poles on the rotor is Bg; pitch of the teeth is τ; and tooth width is Tw. Average magnetic flux density Bg, tooth pitch τ, and tooth width Tw are determined by the equation K=1/(π×Bg×Tw/τ), with the coefficient k in a range of 0.56-0.66 (1/T).
