Motor cogging torque substantially reduced<br />
<br />
New motor technology (patented) is employed to reduce the<br />
cogging torque of motors by about 1/3 through 1/5<br />
(compared to existing model). The smooth motor rotation is<br />
most suitable for applications of high-precision process and<br />
conveyance that are adversely affected by vibrations.<br />
