Question
ECET425L Lab 4: Simple Motor Kit Start
Objectives:
• Given a simple motor kit, study the model to understand the
underlying motor and generator magnetic principles.

Parts List:
• Simple Motor Kit
Introduction
Motors and generators are both considered machines, and both can operate
with either ac or dc. This laboratory briefly explores a dc motor. Permanent magnet dc
motors (PMDC) are dc motors that have poles consisting of magnets. One primary
advantage of these machines is that they do not require a dc field winding, and
they have no associated field winding copper losses, as do their dc shunt or induction
motor counterparts. Permanent magnet motors are typically the most efficient motors
available. It is only because of the high costs of permanent magnets that more of
these motors are not used. The prevailing work horse for generating power to the ac grid
is still the ac synchronous generator. A synchronous generator, like its dc counterpart the
shunt motor, must have its magnetic field supplied by a separate dc power source.

Prelab.
Build the simple motor kit per the instructions given in the provided link.

Procedure A. Simple, Permanent Magnet DC Motor

1. Document any troubleshooting issues you may have encountered in getting the motor to function.

2. Verify that the simple motor rotates, and note how much voltage is needed to turn the motor.

3. Include in your report an oscilloscope screenshot showing the collector to emitter voltage of the BJT.
Make sure to list all supporting details.
What is the applied voltage?
What is the resulting frequency of the waveform?
What is the corresponding rotor shaft speed?

4. Explain in detail how the simple motor works and be sure to include the functions of the reed relay and transistor.

5. Include a photograph in your report of your completed motor.

Questions and Discussion

1. Explain the major differences between a motor and a generator.
