Though they lack the higher efficiencies of their three-phase siblings, single-phase motors — correctly sized and rated — can last a lifetime with little maintenance. Occasionally a manufacturing defect can result in early motor failure.
However, most failures come from inappropriate application. Pay careful attention to application requirements before choosing a motor for replacement of a failed one or for a new design application. Not choosing the correct motor type and horsepower can cause repeated motor failure and equipment downtime. But neither should you specify a motor too powerful — either because of its power or its inherent design characteristics.
It can also have serious effects. For example, a motor with high locked-rotor and breakdown torques can damage the equipment it drives. Also, running a motor at less than full rated load is inefficient, costing you money for power wasted. Download this article in. PDF format This file type includes high resolution graphics and schematics when applicable. First, size the motor to the application but, just as importantly, understand the characteristics of the major types of single-phase motors — characteristics that go right to the heart of matching a motor to an application.
In general, an ac polyphase squirrelcage motor connected to a polyphase line will develop starting torque. A squirrelcage motor connected to a single-phase line develops no starting torque, but having been started by some external means, it runs approximately like a polyphase motor. The many types of single-phase motors are distinguished mostly by the means by which they are started.
It has two windings: The main winding, of heavier wire, keeps the motor running the rest of the time. In most cases, it is a centrifugal switch on the motor shaft. However, it also limits performance. Other split-phase motor characteristics: Plus, thermal protection is difficult because the high locked-rotor current relative to running current makes it tricky to find a protector with trip time fast enough to prevent start-winding burnout.
And, these motors usually are designed for single voltage, limiting application flexibility. Avoid applications requiring high cycle rates or high torque. Like the split-phase motor, the capacitor- start motor also has a starting mechanism, either a mechanical or solid-state electronic switch. This allows higher cycle rates and reliable thermal protection.
But the application range is much wider because of higher starting torque and lower starting current. Use the motors on a wide range of belt-drive applications like small conveyors, large blowers and pumps, and many direct-drive or geared applications. These are the workhorses of general-purpose industrial motors. Permanent split capacitor A permanent split capacitor PSC motor, Figure 3 , has neither a starting switch nor a capacitor strictly for starting.
