  • 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
  • VF Control of 3-Phase Induction Motors Using PIC16F7X7 Microcontrollers
    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
  • 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
  • Why Three Phase Induction Motors Are Popular for Industrial Applications
    and suitable for hazardous environments. *Due to not having brushes, they are long lasting and require minimal maintenance. However, one of the main drawbacks of the 3 phase induction motor is that they have a small, load-dependent speed range. This limits the types of applications induction motors can
  • 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
  • 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
