How do electric motors work?

Electric motors convert electrical energy into mechanical energy for generating motion. Force is produced within the motor through the interaction between a winding alternating (AC) or direct (DC) current and the magnetic field.

What to consider when purchasing a motor?

There are several factors that you need to consider while selecting a motor -

Current is what powers the motor, but excessive current can damage the motor. For DC motors, stall and operating current are important. Stall current applies sufficient torque for the motor to run either at stall speed or 0 RPM. This is the maximum amount of current the motor can draw. Operating current is the average amount of current, motors are expected to draw under specific torque. Overcurrent may lead to shoot up in heat, resulting in wire melting.
Voltage is important as it keeps net current flowing in a single direction and overcomes back current. The higher the voltage, the higher the torque. Make sure that the recommended voltage is applied. If you apply very low voltage, the motor will not work, while applying too much voltage can lead to short circuiting and consequently result in power loss or complete failure.
Operating torque is the amount of torque the motor was calibrated to produce while stall torque is the amount of torque generated when power is applied from stall speed. You must look at the required operating torque, but some applications may require you to know how far the motor can be pushed. For example, with a wheeled robot, good torque means good acceleration but you should make sure the stall torque is high enough to lift the weight of the robot. In this case, torque is more important than speed.
Velocity or speed can be complex in regards to motors. Generally, motors run most smoothly & efficiently at the highest speeds, but it is not always possible if gearing is needed. Adding gears will reduce the motor efficiency, so take into account both the speed and torque reduction simultaneously.

What are the different types of Marathon motors offered by Raptor Supplies?

In addition to general purpose AC motors, Raptor Supplies offers Marathon induction motors, air compressor motors, belt drive motors, brake motors and washdown motors.

What is a TEBC motor enclosure?

Totally Enclosed Blower Cooled (TEBC) enclosure is a totally enclosed motor enclosure mounted with a fan on the opposite end of the motor shaft to deliver cooling air over the motor. Selected Marathon vector motors come with TEBC enclosure to prevent overheating of motor windings.
