Typical courses on electric machines discuss the electromagnetic principles that govern the operation of various ac and dc machines. Equations are provided that build on prior circuit analysis concepts. These equations are often used to ultimately determine torque speed characteristics a given machine of, a given type of machine. However, in the workplace graduates are usually trying to figure out what size machine to use for a given application. Typically, the torque and speed of the machine are needed, as well as the size. To measure the torque, additional equipment is needed which can be quite expensive.
In this paper, a low-cost alternative is presented to give sophomore level electrical engineering technology students a visual understanding of the torque provided by a stepper motor. A steel connecting rod is mounted to the shaft of the motor. The rod can be mounted such that metrology weights can be attached to the rod, allowing the torque applied to the motor to be adjusted.
