<p>An electric appliance adopting novel power source includes a split type power source and at least two appliance main bodies. There are at least two output ports on the power source and the appliance body can be connected to the output ports in splicing. An alternative current servo controller is adopted in the power source and input end of the power source is powered by alternative current electric supply. Permanent magnet brushless direct current motors are adopted on the body of the appliance. The lifetime of appliance is increased and it is energy saving, safe and flexible. It avoids interference on other equipment during the course of operation. Precise high speed braking can be realized. Workers can work by holding the appliance body with rather small weight and small volume, which decreases labor strength of workers, relieves work fatigue and increases work efficiency.</p> |
