Motor Specifications
The motor-application engineer matches operating characteristics and load requirements of an application with motor characteristics to provide dependable, economic service at minimum cost.
For high-volume applications, extensive testing is practical to select the motor best suited for an application by taking advantage of special electrical or mechanical designs.
However, in many applications, because of volume, cost, or expediency, it is desirable to use motors that are available from the manufacturers' stock. These motors are generally called standard, stock, or catalog motors.
EDM uses this standard or stock motor specicfications along with a specific manufacturer's design test results to do the required motor calculations.
