    Motor Description

    • The terminal box of standard motor usually contains 6 winding terminals and 1 grounding terminal at least. Before connecting the motor to the power supply, it must be reliably grounded according to the regulations. Please connect the wiring correctly according to the wiring diagram in the terminal box or on the nameplate.
      When the phase sequence of voltage at the power supply terminal is the same as that of the letter phase sequence of the motor outgoing, the rotation of the motor is clockwise viewed from the shaft extension end. The rotation direction of motor shall be consistent with the direction of motor steering plate (If equipped). To change the direction of rotation, the connection positions of any two-phase power lines can be exchanged.
