How Does Trolling Motor Works?

#

A trolling motor is en electric motor with propeller and controls. Trolling motors are obtainable for both freshwater and saltwater fishing. It can be mounted on three different places i.e. on the transom, on the bow and on the engine itself. A trolling motor simply operates on the principle of electromagnetic induction.

Before discussing about how it works, let us discuss the different parts of trolling motor.

Parts of Trolling Motor

A trolling motor has the following parts:

  • Motor– It is the main part of the trolling motor involved in driving the boat.
  • Propeller– It is fan like component, attached to the motor.
  • Shaft- It is a long stem having the controls.
  • Controls– foot pedal, hand tiller or remote control
  • Power leads with terminal ring battery connectors.
  • Batteries – 12 volts, 24 volts and 36 volts batteries are used depending on the voltage of the trolling motor.
  • Terminal Ends – Used as battery connectors to attach on motor power leads of the battery.
  • Battery Charger – It is required to refresh the trolling motor batteries after use.

How Does Trolling Motor Works

Mounting A Trolling Motor

Trolling motor can be mounted on the transom by the given process.

  1. The clamps of mounting brackets are opened. These motors have 1 or 2 clamps present in the mounting brackets used to hold the motor in place.
  2. The motor is slipped over the center of transom or stern.
  3. The clamps are turned clockwise as far as they go. It should be properly fastened so that the motor won’t loose open when in use.

Working Of Trolling Motor

  • The battery connectors are when connected to the battery, the current start passing through the wires and it goes to the tiller.
  • It helps in controlling the speed and steering of the motor.
  • Foot panel comes directly after the battery connectors. The foot, speed and steer controls are in the foot panel.
  • The trolling motor is mounted on the boat by using the mounting mechanism.
  • The wires reach the motor, lining up to the shaft, which provides a depth to the motor.
  • When the current is put on, it reaches the motor. The motor starts rotating due to the magnetic effect of the current on the coil.
  • As a result of the magnetic effect of the current, the motor starts to rotate. Hence, the propeller which is connected to the motor also starts rotating.
  • The rotation of the propeller produces thrust. The thrust then helps the boat to move in the direction in which it is steered.
  • By giving the accurate amount of charge, the speed of the motor can be controlled. It can be regulated by the controllers.
  • The coil present in the motor has current and is placed between magnets having north and south poles. It produces a magnetic effect. As a result of this the motor rotates.
  • The motor keeps on rotating until the connection is disturbed.

So this is the process in which a trolling motor works. The principle of operation is based on electromagnetic induction. This working process is just the improvement of the old process to increase performance of the trolling motor and get the best out of it.
