How do you make an electric motor?
- Starting in the center of the wire, wrap the wire tightly and neatly around the marker 30 times.
- Slide the coil you made off of the marker.
- Wrap each loose end of the wire around the coil a few times to hold it together, then point the wires away from the loop, as shown:
What Is Design C motor?
“NEMA Design C motor” means a squirrel-cage motor that: (1) is Designed to withstand full-voltage starting and developing locked-rotor torque for high-torque applications up to the values shown in NEMA MG1-2009, paragraph 12.38.2);
What is a design B motor?
NEMA B-design motors are considered to be normal-torque motors. They are used for low-starting-torque loads, such as with centrifugal pumps and fans. NEMA C and NEMA D motors are used for applications that require high starting torque (e.g., positive-displacement pumps and compressors).
How do you choose a motor?
There are several characteristics that you need pay attention to when selecting a motor but voltage, current, torque, and velocity (RPM) are most important. Current is what powers the motor and too much current will damage the motor. For DC motors, operating and stall current are important.

What is Type P motor?
A ‘p’ type motor is a motor specifically designed to support and accommodate the proper form of ‘p’ type protection, so it can safely operate in a given hazardous gas environment. … Once these standards are met, EM can have the motor tested and certified by an Authorized Test Institution if desired by the customer.
What is NEMA standard for motors?
NEMA is the North American standard for electric motors. NEMA is the publisher of NEMA MG 1-2014, a book that defines the manufacturing standards for alternating-current (AC) and direct-current (DC) motors in North America. The IEC is the standard for electric motors for the rest of the world.
What is braking voltage?
DC injection braking is a method of slowing AC electric motors. A DC voltage is injected into the winding of the AC motor after the AC voltage is disconnected, providing braking force to the rotor.
What is kVA code?
A letter code defines the locked rotor current kVA on a per horsepower basis. The letter code consists of letters from A to V. The farther away from the letter code A, the higher the inrush current per horsepower.

How do you make an electric motor more powerful?
We can increase the turning force (or torque) that the motor can create in three ways: either we can have a more powerful permanent magnet, or we can increase the electric current flowing through the wire, or we can make the coil so it has many “turns” (loops) of very thin wire instead of one “turn” of thick wire.
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). If things like wind or current are major factors where you fish, you’ll want a little extra thrust.
