<p>The electromagnetic force acting between a tooth portion and a rotator is expressed by a desired function. The distance L(theta, phi) between the tooth portion (10) and the rotator (2) is determined (step S1). The electromagnetic force Fn(theta, phi) acting in the normal direction of an inner surface (100) is calculated by electromagnetic simulation (step S2). The maximum value M(theta) of the electromagnetic force Fn(theta, phi) at the rotational position phi of the rotator (2) is determined (step S3). The distance between the inner surface of the tooth portion and the outer circumferential surface of the rotator is calculated using a desired function G(theta) (step S4). The maximum value M(theta) is divided by the desired function G(theta) of the maximum value, the square root of the quotient is multiplied by the distance L(theta, phi), the product is used as a new distance L'(theta, phi), and the maximum M(theta) of he electromagnetic force is calculated again (step S5). It is judged whether or not the difference between the new maximum value M (theta) and the desired function G(theta) lies in an allowable range (step S6). IF not, steps S2 to S6 are repeated.</p> |
