  • Speed Control of 3-Phase Induction Motor Using PIC18 Microcontrollers
    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
  • VF Control of 3-Phase Induction Motor Using Space Vector Modulation
    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
  • Understanding Electronic Motor Drives
    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
  • Controlling 3-Phase AC Induction Motors Using the PIC18F4431
    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
  • Will the Small Motor Rule Affect You?
    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.
  • Brushless DC Motor Control Using PIC18FXX31 MCUs
    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
  • Bidirectional VF Control of Single and 3-Phase Induction Motors Using the PIC16F72
    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
  • AN1162 - Sensorless Field Oriented Control (FOC) of an AC Induction Motor (ACIM)
    control, the speed and/or Typical applications requiring the use of an induction position are not directly measurable; their values are motor drive range from consumer to automotive estimated using other parameters such as phase applications, with a variety of power and sizes. voltages and current
