| I use a time switch to control the motor. The switch burns after a while, I don’t know why? So how to control the motor with time switch? (Take 220V single-phase motor as an example) The power of motors on the market starts with kilowatts (kw), and the timing switch directly controls the electrical appliances, and the power that can be carried is 660W, so using a timing switch to directly control a kilowatt (kw) level of motor is definitely easy to burn out. To control the motor with a time switch, an AC contactor must be connected. How to wire the timing switch to control the motor? 1. Connect the mains power (220v) to the air switch (note that the live wire and the neutral wire are in different colors). 2. Connect the air switch and the timing switch (the inlet end on the left). 3. Connect the air switch to the AC contactor, and connect the fire-neutral wire of the air switch to L1 and L2 of the AC contactor. 4. Connect the timer switch and the AC contactor, and connect the fire-zero wire (outlet end on the right side) of the timer switch to A1 and A2 of the AC contactor. 5. Connect the wires of the motor and the AC contactor, and connect the fire zero wire of the motor to the T1 and T2 of the AC contactor (the connection of the single-phase asynchronous motor and the capacitor is not introduced, but we must pay attention). Then check the motor. Close the air switch, open the mobile phone applet, and click Start to see if the motor is running normally. It should be noted that the air switch is disconnected during the entire wiring process. |
