What size electric motor do I need?

General rule of thumb: you need at least 2 lbs. of thrust for every 100 lbs. of fully-loaded boat weight (people and gear included).

How do I know if my electric motor is good?

With a multimeter, measure the resistance between motor frame (body) and earth. A good motor should read less than 0.5 ohms. Any value greater 0.5 ohms indicate trouble with the motor.

Which type of electric motor is most efficient?

Most efficient vehicle in the world uses brushless motor in drivetrain. One little hydrogen fuel-cell vehicle holds the Guinness world record for the most efficient vehicle … and uses a slotless brushless 60L-H-175-A from Koford Motors to drive its rear power wheel.

Why do electric motors lose torque at high rpm?

Because doing so would compromise efficiency and drivability. As engine speed increases, so does it’s inefficiency. Higher RPMs cause more wear, and waste more fuel. For that reason, vehicles usually cruise at a engine speed much below the point where they make maximum power.

How long can an electric motor run continuously?

You should anticipate, given proper attendance, that the motor can run continuously for the life of its brushes, which should be in the range of six months to a year. Presuming that the motor is too small to have its brushes changed by a trained electrician while running.

How deep should a trolling motor be in the water?

12″

What size battery do I need for a trolling motor?

Most trolling motor batteries fail due to lack of proper charging. We suggest selecting a 12 volt deep cycle marine battery with at least a 110 amp hour rating, usually a group 27 size battery. The higher the amp hour rating, the more run time you will receive.

How many horsepower is 55 lbs of thrust?

1/3 hp

How do you check electric motor windings?

Inspect the Motor Windings With a Multimeter

To begin, set the multimeter to read ohms and then test the motor’s wires and terminal. You should test the windings for a “short to ground” in the circuit and open or shorts in the windings.

What causes an electric motor to stop working?

Stressful mechanical, environmental, and electrical operating conditions can all cause electric motor failure. Electrical failures are winding failures caused by an open contactor, bad connection, blown fuse, excessive heat, electrical overload, or broken power lines.

What is more efficient AC or DC motor?

Consequently, AC motors are less efficient than DC motors. In fact, the DC motor is 30% more efficient than AC motors due to the secondary magnetic field being generated from the permanent magnets rather than copper windings.

What are the 6 parts of an electric motor?

These six components include:

  • 1) The Rotor. The rotor is the moving part of your electric motor. …
  • 3) The Bearings. The rotor in your electric motor is supported by bearings, which allow it to turn on its axis. …
  • 4) The Windings. …
  • 5) The Air Gap. …
  • 6) The Commutator. …
  • What Do All of These Components Have in Common?

Can an electric motor generate electricity?

Converting energy from one form to another is the key to understanding the differences between electric motors and generators. An electric motor converts electricity into mechanical energy, providing a power source for machinery. A generator does the opposite of this, converting mechanical energy into electricity.
