Run submersible motor without starter | Motor starter connection

Run submersible motor without starter:

This diagram shows how to make a Run submersible motor without a starter. Motor starter connection. In this circuit, we use a DP MCB ( Double Pole Miniature Circuit Breaker ), a starting capacitor, a running capacitor, and a submersible pump. We need to connect all components like our diagram. Now this circuit is ready for use. If you want to know more about this circuit please check our youtube video below the post.

Components used to make the Motor starter connection:

01. DP MCB

DP MCB
Fig 2: DP MCB


Double pole MCB can control two wires. This circuit breaker is generally used in single-phase electric lines. Double pole MCB circuit breaker input has two wires supply two wires and an output. In a single-phase line, A double-pole MCB circuit breaker is used to give good production. This circuit breaker is provided through phase and neutral circuit breaker, it is very safe. This circuit breaker is preferred for home appliances. A DP MCB usually trips for 2 reasons 1. Overload 2. Short circuit.

02. Starting Capacitor

Starting Capacitor
Fig 3:Starting Capacitor


The purpose of the starting capacitor is to provide sufficient torque to start the motor and disconnect from the circuit after the motor reaches a predetermined speed. When voltage is applied to the motor without the start capacitor, the motor will make a humming sound. A start capacitor's capacitance range is between 70 and 120 microfarads. The Start Capacitor Increases The Motor Starting Torque and Allows The Motor to Cycle and run Faster. The Start Capacitor is Designed in Such a Way That it is Used for a Short Time. They cannot stay strong for long.

03. Running Capacitor

Fig 4: Running Capacitor


A Run Capacitor is Used in Single-Phase Motors to Maintain a Running Torque on an Auxiliary Coil While The Motor is Toaded. These Capacitors Are Considered Continuous Duty While The Motor is Powered And Will Remain in The Circuit While The Starts Capacitor Drops out. The Run Capacitor, Also Sometimes Called an “A/C Capacitor,” Uses Its Stored Energy to Turn or Run The fan Motor. Without The Run Capacitor, The Fan Cannot Turn. Run Capacitors Are Also Rated by Voltage Classification. The Voltage Classifications are 370V and 440V.
