CAS DataLoggers recently helped a frozen product manufacturer to monitor temperature and perform power factoring on several large 3-phase compressor motors used for refrigeration. As these compressors aged through valve leakage and piston ring deterioration, the AC temperatures fluctuated which...

...than the PIC18F452 or PIC16F7X7. Practically speaking, control of a 3-phase AC induction motor requires pulse-width modulated control of the six switches of a 3-phase inverter bridge connected to the motor's stator windings (Figure 1). The six switches form 3 pairs of "half-bridges", which can...

Single-phase induction motors are extensively used in appliances and industrial controls. The Permanent Split Capacitor (PSC) single-phase induction motor is the simplest and most widely used motor of this type. By design, PSC motors are unidirectional, which means they are designed to rotate...

Induction motors are the most widely used motors for appliances, industrial control, and automation; hence, they are often called the workhorse of the motion industry. They are robust, reliable, and durable. When power is supplied to an induction motor at the recommended specifications, it runs...

An induction motor can run only at its rated speed when it is connected directly to the main supply. However, many applications need variable speed operations. This is felt the most in applications where input power is directly proportional to the cube of motor speed. In applications like...

VF control using the Sine PWM algorithm is a popular algorithm for AC induction motor control; however, this algorithm has certain drawbacks which affect the overall system efficiency. A more advanced switching algorithm, like Space Vector Modulation (SVM), overcomes the drawbacks of the Sine PWM...

...that require reliable, efficient motor operation in hazardous or wash-down environments. It responds to input signal changes in as little as 5 msec, covers a 0.5 to 3-hp range, and an input voltage range of 380 to 500 Vac three phase. The rotor and stator work through magnetic interaction...

...for Open Drip Proof, General Purpose motors in both single and three phase designs. Dubbed the Small Motor Rule, horsepower ratings covered include 0.25 thru 3 HP (and kW equivalents) with speed ranges of 1,200 - 3,600 RPM operating from 60 Hz frequency....

A 3-phase brushless motor requires the amplifier to provide electronic commutation. Commutation of a brushless motor means that the amplifier needs to decide which phase of the motor to energize and at what point in the magnetic cycle to energize it. Standard Galil 500W amplifiers require hall...

A PICDEM TM MC demo board was used to develop, test and debug the motor control code. The PICDEM MC has a single-phase diode bridge rectifier, converting AC input to DC and a power capacitor bank that keeps a stable DC bus. A 3-phase IGBT-based inverter bridge is used to control the output voltage...
