1PCS 220V 650W/750W Motor 4000 rpm/7000 rpm Double Bearing CW CCW For Grinding Polishing Drilling Micro Machine Tools(750W 7000RPM,Only motor)

Generators220V 650W/750W Motor 4000 rpm/7000 rpm Double Bearing CW CCW For Grinding Polishing Drilling Micro Machine ToolsNotice :(1) The motor is a 220V carbon brush motor and must be connected to the provided rectifier bridge to use 220V AC power; If you want to connect the speed controller from our store, you can directly connect it without the need for a rectifier bridge (the speed controller has a built-in rectifier bridge).(2) Due to the high motor speed and complete closure, it cannot be used for a long time. Generally, 4000 rpm is controlled within one hour. Control 7000 rpm within 30 minutes. If used intermittently, it can be used for a longer period of time. As long as the temperature does not exceed 85 degrees, it is considered normal temperature.(2) Never directly connect the motor to 220V AC power. If it is connected incorrectly and burned out, our store will not be responsible.(4) Problems arising from using speed controllers:1. The power and force of the motor will decrease as the speed decreases;2. Some motors may experience vibration, so it is recommended to add a filtering capacitor for better performance. But it will not be completely eliminated;3. If you want to slow down but don't want to lose power, you can use wheels and belts to solve it; But this output only has a fixed speed;4. wheels and speed controllers can also be used simultaneously for deceleration; Precautions for using forward and reverse speed controllers: must start from forward to stop to reverse; Never go directly from forward to reverse. This will burn out the motor; It's very dangerous!!Problems arising from using the governor:1. The power and force of the motor will decrease as the speed decreases;2. Some motors may experience shaking, so it is recommended to add a filter capacitor to improve the performance. But it will not be completely eliminated;3. If you want to reduce the speed without reducing the force, you can use wheel and belt; But this output only has a fixed speed;4. It is also possible to use wheels and speed regulators simultaneously to slow down; Precautions for using a forward and reverse speed governor: it must start from forward to stop to reverse; Never directly turn from forward to reverse. This will burn out the motor; It's very dangerous!! The motor and our governor can be connected in red and black, without the need for a bridge. Be sure to connect the wires first and seal them with insulating tape. Then turn on the power again. When using forward and reverse rotation, remember to stop in the middle and then reverse the direction. Do not let the motor rotate in the forward direction. You will switch to another direction in one go. Motor*1 or Motor with bracket*1==========Construction : Permanent MagnetProtect Feature : Totally EnclosedCommutation : BrushOutput Power : 650W/750W
