Many areas of industries demand consistent performance from their power tools, generally conventional angle grinders fail to meet the high performance requirement, since it has inherent losses of power due to its design, which has a universal motor consisting of field coil, armatures, carbon brush, holders etc. These types of motors have generally a speed drop of 30 to 40% (i.e. if the grinder is rated for 8500 rpm on no load, at full load it drops to almost 5000 to 5100 rpm) which results in less material cutting and more consumption of cutting wheels and energy, hence heavy maintenance costs. To overcome this entire problem a technology of high frequency brush less power tools proves to be an outstanding solution. The solution is the perfect answer that meets the demand of high power productivity, lowest maintenance, overall top performance for the demanding heavy grinding applications.
