What can you use an electric motor for?
The largest electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts. Electric motors are found in industrial fans, blowers and pumps, machine tools, household appliances, power tools and disk drives.
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 what motor is right for me?

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?
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 long do electric boat motors last?
The larger the rating, the more power the battery can hold, and the longer it will be able to power a motor at a given speed. For example, a 100 amperage hour battery is one that would be able to supply 25 amps of power for 4 hours (25 amps * 4 hours = 100 amp hours) before running out of energy.
How do you check if a motor is AC or DC?
Look for the stator core construction and rotor. If there is no commutator, then it is a AC motor. If there is a commutator and brushes, it may be either a DC motor or an AC commutator motor (Universal motor).
How can you identify an electric motor without nameplate?
If there is no name plate, you won’t be able to know the rated voltage too. In that case, you may have to guess the approx. HP depending upon the size of the motor, select appropriate auto transformer and then run at no load by slowly increasing the voltage till it reaches steady state.
How can you tell if a motor is 3 phase?
Second you can simply look at the number of electrical leads coming out of the motor. If your motor has three black leads and a green lead then it is likely three phase. The three hot leads are usually labeled U, V and W and the final lead is labeled ground. Running a three phase motor on single phase power is simple.
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 do you select a pump motor?
When choosing a motor for a centrifugal pump, you must consider the impeller size, maximum capacity, specific gravity of the fluid, and service application in case API requirements apply. If you take these things into account, you will select the right motor for your centrifugal pump application.
Which motor is used in tramways?
This paper compares five different motor types used in variable speed drives: a dc motor with a mechanical commutator and with electromagnetic or permanent magnets excitation, a cage induction motor, asynchronous cascade with a slip‐ring motor and a brushless motor with PM excitation.
