Title: SYNCHRONOUS LINEAR MOTOR
Abstract:
To improve the movement precision of a synchronous linear motor, it is proposed that the front and rear 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 (β) of the bevelled surfaces (11a, 12a) on the front and rear faces (11, 12) of the primary section (10) in relation to the longitudinal axis (13) of the motor is selected according to the relation: β=arctan (b/τp) where β is the angle of inclination of the bevelled surfaces (11a, 12a) at the front and rear faces (11, 12) of the primary section (10), b is the electrically active width of the primary section (10) and τp is the pitch of the poles (21, 22) of the secondary section (20).
