Analyses & Solution
Initial idea was to use a high-efficiency electric motor to reduce the capacity of the battery pack. But there was a problem. Not only the high-efficiency electric motor price are higher than low efficiency one, but also initial cost including design and development of new motor would impose lots of cost to the manufacture.
Detailed cost estimation and the market search revealed that the reduction in the battery cost is considerable and can compensate electric motor initial and production cost.
In the next step, Lian Innovative carefully proposed a business plan to replace old fashion BLDC motor, by a new modern high efficiency, Light, PMSM hub wheel motor and reduce the capacity of the expensive Lithium ion battery pack to about one half. By this shift, the initial cost of the new design could be refunded by saving in the battery price in first 5324 Electric Motorcycle and after that the total production cost reduced by 36%. Which keep the product competitive in the market.
A custom designed enhanced PMSM hub wheel motor was designed and developed and a prototype were manufactured. Also, new low capacity lithium ion battery pack was design and developed and a prototype was manufactured.
