Purchase of electric motors to mark the direction of the junction box

Purchase of electric motors do not necessarily have to mark the direction of the junction box, generally are not indicated for the normal, if there are special requirements will be indicated, such as the left outlet, indicated on the nameplate of the motor, the physical can be seen what is out of the line, according to the location of the outlet box holes can be divided into the left, the right (normal) on the line.

Motor (Motor) is a device that converts electrical energy into mechanical energy. It is the use of energized coil (that is, stator winding) to produce a rotating magnetic field and act on the rotor (such as squirrel cage closed aluminum frame) to form a magnetoelectric power rotating torque. Electric motors are divided into DC motors and AC motors according to the use of different power sources, most of the electric motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (motor stator magnetic field speed and rotor rotational speed does not maintain synchronous speed). The motor consists of a stator and a rotor, and the direction of the force on the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic inductance (direction of the magnetic field). The working principle of the motor is the action of the magnetic field on the current force, so that the motor rotation.

The use and control of electric motors is very convenient, with self-starting, accelerating, braking, reversing, stopping, etc., to meet a variety of operational requirements; motor efficiency is high, and there is no smoke, odor, do not pollute the environment, the noise is also smaller. Because of its series of advantages, so in industrial and agricultural production, transportation, national defense, commercial and household appliances, medical equipment and other aspects of the widespread use of electrical equipment.
