PCT No. PCT/EP96/02684 Sec. 371 Date Mar. 27, 1997 Sec. 102(e) Date Mar. 27, 1997 PCT Filed Jul. 20, 1996 PCT Pub. No. WO97/05688 PCT Pub. Date Feb. 13, 1997To improve the movement precision of a synchronous linear motor, it is proposed that the front and rear end faces (11, 12) of the primary section (10) be ungrooved and not wound and bevelled in sections in such a way that the angle of inclination ( beta ) of the bevelled surfaces (11a, 12a) on the front and rear end faces (11, 12) of the primary section (10) in relation to the longitudinal axis (13) of the motor is selected according to the relation: beta =arctan (b/ tau p) where beta is the angle of inclination of the bevelled surfaces (11a, 12a) at the front and rear end faces (11, 12) of the primary section (10), b is the electrically active width of the primary section (10) and tau p is the pitch of the poles (21, 22) of the secondary section (20).
