How do I find my motor details without nameplate?
Use a strobe tachometer to determine motor RPM and then set up a generic motor in the database for that RPM. If loading cannot be provided by the operator use the acquired data and RPM to approximate loading. You can view the power factor for a value around 88 to 92 to approximate full load.
What is the difference between 48 Frame and 56 Frame motor?
The main difference between a 48 frame and a 56 frame hot tub pump is that the 48 frame has a smaller motor housing and so the 4 through bolts that fasten the wet end to the motor are closer together on the smaller motor.

The J suffix relates to a motor with a face mount for jet pumps and in the case of a 56J motor frame the distance from the mounting location shoulder outer face to the shaft end is 2 7/16". Also, the shaft end is threaded on this type.
Should engine and frame numbers match?
Matching Numbers Early motorcycles generally had the same number for the engine and frame (often referred to as matching). However, occasionally an engine case (containing the original number) may have been replaced due to damage and will not, therefore, have a number stamped on it.
What does C face motor mean?
• C - Designates a “C” face (flange) mounted motor. This is the most. popular type of face mounted motor and has a specific mounting bolt pattern. The critical items on C face motors are the “bolt circle” (AJ dimension), register (also called the rabbet) diameter (AK dimension), and the shaft size (U dimension).
How do you read a motorcycle chassis number?

What is the unit of measurement used to determine the size of a servo motor?
Let’s begin with a review of a few key terms and the units of measurement used to determine your servo motor size. 1. Moment of Inertia. The manufacturer of servo motors will need to know the force required to move the load. The force to overcome the loads resistance is called Moments of Inertia.
Can you manually select servo motors?
Some learners will enjoy performing the motor selection calculations manually, (we will briefly illustrate and describe some of the calculations later on in this lesson), while others prefer, utilizing one of the many online programs available to help you with all the necessary specifications of the servo motor required for your project and expediate you through the servo motor selection process.
