This paper is to research about design and drive system of a switched reluctance motor for a pallet truck application. SRM is suitable for a pulse type source and is researched for home and industrial applications owing to the advance of power electronics technology. An SRM for a pallet truck drive is developed and tested. The drive system has to operate with low voltage and high current. The small size, robustness and high efficiency make it possible to replace with DC motor which is used in a pallet truck conventionally. Test results show that pallet truck with SRM has better drive characteristics than that of the DC motor.

BLDCM(Brushless D.C. Motor) is widely used for industrial application because of high efficiency and high power density. Especially, in servo system and home appliance, BLDCM is very useful due to high control performance and low acoustic noise. In this paper, 2.5HP rated BLDCM and its controller is developed for tread mill application. The prototype BLDCM has 4 poles rotor and 24 slots stator. Ferrite magnet was used as a rotor magnet because of the cost and temperature characteristic. For the stable operation of tread mill, current and temperature can be detected and treated by DSP. Thedesigned BLDCM and its controller is verified by the experimental results.
