220V/350W High-speed Adjustable Speed Electric Grinder and Bench Drill DC Motor

2. The motor needs to be connected to the complimentary rectifier bridge to use 220V AC, remember to use 220V AC directly! If you buy a set with speed regulator, connect the motor with the speed regulator can be, do not need to connect the rectifier bridge; motor is a carbon brush motor, the speed of no-load about 7000 rpm, error 5-8%. Speed range 700 rpm-7000 rpm, the lower the speed, the less power, when the load is too large, it will burn the motor or governor, so it is recommended that the governor for fine-tuning. 3.This 350W motor has been added internal cooling fan, can run for a long time (according to the load size control within 1-2 hours)! 4.B12 collet is a triple gull, the factory has a 25 silk error, demanding buyers please buy ER clamps directly; 5. This connection set because there is no synchronous wheel deceleration, so it can not be compared with the market with reduction gears of the table drill Oh. 6. If you want to drill large holes, or to the metal drilling, you need to use a powerless spindle to modify; can not be used directly, burned off is not responsible. Problems arising from the use of governor: 1, the motor power and strength will decrease with the speed; 2, individual motor will have jitter, it is recommended to add a filter capacitor, it will be better. But it will not be completely eliminated; 3, if that want to reduce the speed, but do not want to reduce the power, you can use synchronous wheels, synchronous belt to solve; but the output of such a fixed speed only; 4, you can also use the synchronous wheel and governor to slow down at the same time; positive and negative governor use of caution: must be from positive - stop - reverse; never, never directly from positive - reverse. This will burn the motor; very dangerous! 5, connected, must be sealed with insulating tape, and then energized. Prevent the motor or other accessories burned due to short circuit.
