Electromagnetic Design and End Effect Suppression of a Tubular Linear Voice Motor for Precision Vibrating Sieves
Precision vibrating sieves need a kind of power source, featuring small size, high frequency response, and small vibration amplitude. Linear Voice Coil Motor (LVCM) can achieve a high accelerated speed in a short stroke; it is an appropriate power source for the precision vibrating sieves. This pape...

| description | Precision vibrating sieves need a kind of power source, featuring small size, high frequency response, and small vibration amplitude. Linear Voice Coil Motor (LVCM) can achieve a high accelerated speed in a short stroke; it is an appropriate power source for the precision vibrating sieves. This paper designs a tubular LVCM with a volume no more than 6 cm<sup>3</sup> and a stroke no less than 1.5 mm. The electromagnetic topology of this LVCM is established to validate its feasibility; the back Electromotive Force (back EMF) and the electromagnetic force are calculated. The end effect of this tubular LVCM is studied in detail; the auxiliary pole and the magnetic conductive stator base are designed to suppress its end detent force. Then, the main structure parameters are globally optimized by the multi-objective genetic algorithm to obtain better performance. The prototype of this tubular LVCM is manufactured and tested. The results of the experiments are compared with those of theoretical analyses. It is indicated that this tubular LVCM can provide an accelerated speed of 15<i>g</i>; <i>g</i> is the gravitational acceleration. |
