A Motor Converts Electrical Energy Into Mechanical Energy ◦ AC Alternating Current Reverses Poles of Electromagnetic Coil 120 Times Per Sec (60hz) ◦ Coils Wound into the Stator of the Motor Create Rotating Magnetic Field ◦ Magnetic Field Passing Through the Conductors of the Rotor Induces Current to Flow ◦ Induced Current Produces Magnetic Field Around Rotor Conductors Which Creates Magnet ◦ Rotor and Shaft Follow the Rotating Magnetic Field of the Stator
Most likely your operation’s motors account for a large part of your monthly electric bill. Far too often motors are mismatched—or oversized—for the load they are intended to serve, or have been rewound multiple times. To compare the operating costs of an existing standard motor with an appropriately-sized energyefficient replacement, you need to determine operating hours, efficiency improvement values, and load. Part-load isa term used to describe the actual load served by the motor as compared to therated full-load capability of the motor. Motor part-loads may be estimated through using input power, amperage, or speed measurements. This fact sheet briefly discusses several load estimation techniques. Reasons to Determine Motor LoadingMost electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency isusually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor’s efficiency tends to decrease dramatically belowabout 50% load. However, the range of good efficiency varies with individual motors and tends to extend over a broader range for larger motors, as shown in Figure 1. A motor is considered underloaded when it is in the range where efficiency drops significantly with decreasing load. Figure 2 shows that power factor tends to drop off sooner, but less steeply than efficiency, as load decreases.
Motor Speed Relationship ◦ The Synchronous Speed of an AC Motor Is the Speedof the Rotating Magnetic Field Set up by the Stator Winding ◦ Synchronous Speed (RPM) = (120 X Frequency) Divided by the Number of Poles. i.e. 120 x 60Hz / 4- Poles = a Base Speed of 1800 RPM ◦ As Load Torque Is Required From the Motor, Rotor Speed Will Decrease Relative to the Rotating Field. This Is Called “Slip” ◦ “Slip” Induces Current to Flow in the Rotor Which Interacts With Rotating Field and Produces Torque Which Is Transmitted to the Load ◦ Synchronous Motor With Reluctance or Permanent Magnet Rotor Have No Slip and Provide Exact Speed up to Full Load Rating
