...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...

This provides higher efficiency, lower operating costs and reducesThe requirement of low-cost, low-maintenance, robust the cost of drive components.electrical motors has resulted in the emergence of the AC Induction Motor (ACIM) as the industry leader. In sensorless field oriented...

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...

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...

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...

A Variable Frequency Drive (VFD) regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. Today, these devices (also known as Adjustable Speed Drives or Variable Speed Drives) are becoming prevalent in a wide range... engine power. The Escape Hybrid augments the engine's lower power with a 70-kW (94-hp) permanent-magnet ac-synchronous electric motor. Driving the Escape Hybrid breaks down into five distinct phases.
