The frame size is often a part of the type designation which can be difficult to interpret because special shaft or mounting configurations are used.
How to choose the right motor for your application?
These are the basics to consider while selecting a motor. Consider an application’s purpose and which current it uses to select the appropriate type of motor. An application’s specifications such as voltage, current, torque, and velocity will determine which motor is most appropriate so be sure to pay attention to its requirements.
What should I look for before installing a motor?
When receiving a motor, you should thoroughly inspect it for dents or other signs of damage before the motor is moved from the shipper’s truck. Also, examine all literature provided with the machine.
Why do you need a stepper motor in a printer?

If you ever need to size a VFD, repair a motor, replace a motor, connect a motor, correct power factor, purchase parts, or do just about anything with a motor you will need the information on the motor nameplate. Horsepower is the mechanical output of a motor.
Can a motor have three different frame sizes?
In these motors, specific frame assignments have not been made by horsepower and speed, so it is possible that a particular horsepower and speed combination might be found in three different frame sizes. In this case, for replacement it is essential that the frame size be known as well as the horsepower, speed and enclosure.
What are the different sizes of fractional horsepower motors?
The frame sizes that are normally associated with industrial fractional horsepower motors are 42, 48, and 56. In this case, each frame size designates a particular shaft height, shaft diameter, and face or base mounting hole pattern.
What should be considered when installing a motor?
Moisture problems require special consideration. Here, suitable guards or enclosures must be provided to protect exposed current-carrying parts and the insulation of motor leads where dripping or spraying oil, water, or other injurious liquid may occur, unless the motor is specially designed for the existing conditions.
