MAT 2030 - Motors

• Explain magnetism and the part it plays in the operation of electric motors.
• Explain torque and the purpose of different types of single-phase motors.
• Explain the operation of a basic electric motor.
• Understand how to operate, install, reverse the rotation (if possible), and diagnose problems in a shaded-pole motor.
• Understand the purpose of capacitors in the operation of a single-phase motor and be able to explain the difference between a starting and running capacitor.
• Correctly diagnose the condition of any capacitor and, using capacitor rules, be able to substitute a capacitor if a direct replacement is not available.
• Explain how to operate, install, troubleshoot, and repair (if possible) split-phase and capacitor-start motors.
• Explain how to operate, install, troubleshoot, and repair (if possible) permanent split-capacitor motors.
• Explain how to operate, install, troubleshoot, and repair (if possible) capacitor-start-capacitor-run motors.
• Understand how to operate, install, reverse, and troubleshoot three-phase motors.
• Explain how to operate, install, troubleshoot, and repair (if possible) electronically commutated motors.
• Identify the common, start, and run terminals of a single-phase compressor motor.
• Identify and explain the operation of motor starting relays and other starting components that are used on single-phase hermetic compressor motors.
• Select the correct potential relay for an application with information available on the potential relay to be replaced.
• Troubleshoot and install motor starting relays on hermetic compressor motors.
• Lubricate and identify the types of bearings used in electric motors.
• Identify the type of motor drives used on industry applications.
• Calculate the variables in a V-belt drive application to obtain the desired equipment rpm.
• Recognize and adjust a V-belt application to the proper tension and alignment.
