The development of lithium brushless electric Angle grinder

Traditional Angle grinder, Angle grinder, after decades of evolution and development from the original large size, heavy, need two people together operating characteristics, development to today's small and light, power strong, single single hand operation, even a great progress. At the same time, the development of Angle grinder and the development of the industry all over the world play a huge role. But plus ca change, the development of the Angle grinder has been inseparable from one of the material - — Carbon brush. Carbon brush is a kind of industrial consumables, used for dc motor or ac motor commutator, such as general electric tools, such as hand electric drill and Angle of grinding machine, use it. It is used to and cooperate to achieve motor current commutation commutator, carbon brush motor ( In addition to the squirrel-cage motor) Sliding contact conduction of electric current. In dc motor, it also shoulders the alternating emf induction in the armature winding, reversing ( Rectifier) The task. The practice proved: the reliability of the motor running, to a large extent depends on the performance of the carbon brush. All the grinder users had to replace carbon brush experience, most people a headache. With carbon brush is enclosed within the chassis, not intuitive see carbon brush wear degree, must be opened casing or unscrewed the special carbon brush seal. If the user in the carbon brush wear out before did not change in time, will have the following consequences: first: after the machine stops working, replace carbon brush can continue to work, The lightest consequences) Secondly, after the carbon brush wear, to resist carbon brush at the bottom of the metal shrapnel, come into direct contact with the rotor copper head rotor damage, need to change the rotor ( Moderate consequences) Third: short circuit, cause sparks, produce high temperature, the rotor stator all burn out, nonmetal melting, the machine scrap, and even endanger the life safety users ( Serious consequences) Brushless grinder: it is because of the traditional Angle mill need to change the shortcomings of the carbon brush can't resolved, lithium brushless electric Angle grinder to arises at the historic moment. Is worth rejoicing, after China's industrial technical personnel's unremitting efforts, has now developed by fujian cayon electric tools co. , LTD is the first generation of lithium brushless electric Angle grinder, and obtained the national patent. Put on the market, has been widely welcomed by the majority of users. The machine does not need to transfer carbon brush, rotor by solid silicon steel sheet suppression and become, no metal coil winding, durable. , switch button, if there are any power supply energized again when the power is at work, not to start the machine, reduce the happening of the accident, use more secure. , no carbon brush, eliminate the effects of carbon brush powder on body for operators to dispense often replace carbon brush. Without carbon brush and copper head friction sparks, explosion-proof effect, also not interfere with the signal around the circuit. , assembling brushless motor without carbon brush and copper head friction produced by the electricity consumption and frictional resistance, power output ratio compared with the traditional Angle grinder % above. The machine in normal working conditions, can maintain the rated speed, make the work more efficiently, and at any time don't have to consider to replace carbon brush, also need not worry burn rotor, the use of more efficient. , motor speed slow start when the phone is switched on, won't produce a spin phenomenon, more comfortable to operate. And because it is a slow start, effectively reduce the moment of the motor starting current, more effective to extend the life span of the motor and related equipment. , motor rotor made of high strength silicon steel sheet, and is not a traditional rotor coil winding way, never burn rotor. , in addition to bearing and gear to normal maintenance, the machine there is no other parts. To minimize the maintenance cost.
