Motors 101: How do a SP, PSC, and EC Motor Compare?

Looking to learn more about the different types of motors out there and which one may be right for your business? Here is a brief rundown on the three most popular types. 

Shaded Pole Motor

• The cheapest motor due to the older design and technology
• Typically used for light ventilation applications
• The least efficient motor because it generates the most heat versus power applied
• Around 30% efficiency

PSC (Permanent Split Capacitor) Motor 

• Most commonly used motor
• A capacitor is usually used to help run the motor and generate more torque
• These motors can run either single or multiple speeds.
• A PSC motor is usually 40-60% efficient, meaning you're only going to get about 40-60% output power from the motor

EC (Electrically Commutated) Motor

• The smartest motor currently available
• More expensive motor but you gain high efficiency
• Typically has a printed circuit board inside to get feedback on its environment
• 70-82% efficient and can see ROI within a year
