Abstract

Divide armature into a plurality of armature blocks 4, 5, 6 and line them up along the pushing force. Install armature coil 11 as concentrated roll with integer fold of teeth 10 lined up with equal pitch on the armature block core 9. Put electrical angle gap equivalent to the integer fold of the value by dividing armature block number by magnetic pole pitch in the said armature blocks. By means of the shift phase done by the electrical angle gaps among armature blocks corresponding to the armature coil of each armature block, the teeth matching force generated by each armature block provides phase difference, making the sum of that zero as a result of counterbalance.

In this way, since the magnetic circuit of the armature core moved by the conventional moving coil type linear motor system has not been circulated and is opened at both ends, the slot systems at the two ends of the armature thrust direction are different from the slot holes at the center. Only one coil is accommodated, and an end effect occurs through the slot, and a period of cogging torque TC occurs in the magnetic pole pitch of the field magnet, and uneven thrust occurs. ’In order to implement the temperature management of the coil, when the temperature sensor is inserted into the slot for storing the coil, the slot must be enlarged, and the armature core becomes larger, which reduces the winding occupation ratio. In this way, temperature sensors are required to be installed at the two ends of the linear motor system, but the temperature of the central part of the coil cannot be measured, so it is not possible to apply the Chinese National Standard (CNS) A4 specification (210 X 297 mm) to this paper size ---- -h ------ · install ----- r (please read the precautions on the back before filling this page) 1T --------- line-4-486849 employee of Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the consumer cooperative A7 B7 V.

The excitation magnetic pole 1 can be a permanent magnet type or a winding excitation type. It is arranged at an equal pitch P m in the linear motor stroke plus the length of the armature 3 in the thrust direction. Since the magnetic pole pitch p is equal to the electrical angle of 180 ° ', the clearance dimension pm X% is set at the electrical angle of 120 °. In this case, the tooth pitch P t is taken as the electrical angle 120 °. In this way, the armature coil arrangement of each armature block 4, 5, 6 is as shown in Fig. 2 (a /).

In the figure, the fixing mechanism 8 of the armature blocks 4 and 9 is shown for ease of explanation. The armature blocks 4 and 9 are arranged below the field poles 1 in parallel. The basic structure of the armature is the same as the fifth paper size applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) -27-486849 A7 B7 V. Description of the invention (25) The implementation form is the same. The side sectional view is the same as that in FIG. 13 at the center. (Please read the phonetic on the back?

Each of these inclination angles 0 is the product of the armature block width as W, and the magnetic pole pitch as P m, set to 0 = s 1 n ^ 1 (Pm / 2W), that is, the inclination into the electrical angle (mechanical (P m / 2). In the following, the effect of this embodiment is compared with that of the fifth embodiment.
