The difference between high voltage motor and general motors
A high voltage motor is defined by a voltage difference. For example, the high voltage motor is considered to be 1000V, 380V, 660V for low voltage motor. A general motor is a relative special motor. Such as drag pump, fan, compressor, crusher and so on. A high voltage motor is a motor that is rated at 1000V. The usual use is 6000V and 10000V voltage, which also has a voltage rating of 3300V and 6600V due to the different power grids in foreign countries. High voltage motor is due to the motor power is proportional to the product of the voltage and current, so the low voltage electrical power increases to a certain degree (such as 300 kw / 300 v) current limited to allow bear ability of the wire is hard to do big, or too expensive. High power output is required by increasing voltage. High voltage motor has the advantage of power and high impact ability. The drawback is that inertia is hard, starting and braking are difficult.
Main is the grade of power supply voltage is different, the factory high voltage motor general electric power supply voltage is 6KV, low voltage motor is commonly 220V / 380V. The structure comes in, the high voltage motor is synchronous and asynchronous machine, low voltage motor is asynchronous motor.
The difference first is that in the voltage, the common motor that is common in the industry is not distinguishable, usually, 380,550,750,800. On the upgrade is usually the medium voltage motor for communication, and I have been debugged with two voltages of 1650 and 3300. The next level is the high voltage motor, which is more than 6000.
The motor of a sliding bearing is not allowed to reverse, but can be reversed in a short time. The reversal brings a lot of problems, but the wind path is one of them, but not all of it. Sliding bearing of the bearing should be oil wedge, it is be from bearing lubricating oil entrance into bearing shell structure, if the reversal of the oil wedge also does not work, it is possible to process (estimate for such a big motor shall be equipped with bearing shell temperature measuring point, normal temperature is high?) It is. So let's make it positive. Only the blades can't solve the problem completely. Consider the following options: 1. Please modify the motor (axle, wind, etc.). Install the motor on the other side of the fan. Add a 1:1 gearbox and change the turn

Such as drag pump, fan, compressor, crusher and so on. Special motors such as Marine, explosion, traction, diving, etc. Most of the high-voltage motors are general motors. Ordinary motors have a lot of electric motors.
