Hello,I would like to control the speed of an AC single phase motor I constructed the ciruit as you find in attachment.I have the following problem which I would like you to help me solving: >>Whith the snubber of 1nF/250V(shown by multimeter) and 1.5Kohm is not allowing the PIC to control the (...)
The load of a compressor is an electric motor. So it all depends on the size of the motor, so 100W 230 single phase to 20kW 415V 3phase for commercial installations. Frank
What should be AC fuse rating & NTC (-ve temperature coefficient) rating for single phase 230 VAC, 50 Hz, 1 KW AC drive (Max input current is 10 A)??
Do avoid the noise you could used some form of higher-frequency PWM control that uses MOSFETs and not SCRs such as this, but I don't know if those are avail
Perform single steps, either in half- or full-step mode. Verify the individual A-D and motor phase signals.
i am doing my FYP on synchronization of two single phase alternators at 100Hz. i have complete one set(speed control module>12 V dc motor>alternator 150W) and put that on a board. this gives a pure sine wave. now i put another DC motor and alternator on board. now to synchronize the second alternator with (...)
hello everyone, i want to know that is there an h-bridge inverter module exists? i have my final year project which is variable frequency drive (speed control of single phase ac induction motor). i have generated spwm signals using pic mcu through which i can achieve variable frequency. however, i am stuck with the (...)

Hello sir, I am really confused that how to control the speed (rpm) of my single phase 1 HP Servo motor using PWM by PIC16F877A micro-controller. What hardware and Code should i use to interface my 1 HP servo motor with PIC16F77A for controlling it's speed. (...)
It is difficult to control a single ph motor using v/f=const. Torque of motor is proportional to V*V. So reducing speed by a small amount reduces the torque to square of it. For wider range successful speed control, use DTC or Vector ctrl.
All induction motor have speed proportional with frequency. When reduce frequency, alson need to reduce voltage to keep same flux. This is automaticaly made by inverter in various mode (depend of control method); when reduce voltage by k, torque is reduced by k^2, so torque may became very low at small speed. May try to use 3-phase (...)
Good day! I saw this code in the internet for single phase AC motor Speed control using TRIAC. The existing project used AVR microcontroller. I would like to ask help from anyone here who's familiar/knowledgeable in both PIC and AVR in transferring and translating it to PIC18 (both are written in C). The (...)
Good day everyone! I'm new here and I'm new to PIC programming.. I would like to ask help from you guys.

how do i interface a vfd drive(single phase induction motor) using a plc. 1. the application is i have a mixer chamber that is to be driven by single phase induction motor using vfd i need to control the speed of the motor to get desired results. (...)
Microchip has published application notes with circuit suggestions for small motor inverters. single phase induction motors are either shaded-pole motors or split-phase motors with a starting or permanent capacitor. Capacitor motors would be driven by a (...)
First, rectify the single phase AC to DC. Then, use a 3-phase bridge rectifier to convert the DC to 3-phase AC. Use a microcontroller to generate the SPWM signals. Generate the signals 120' out of phase. You can use a dsPIC30 or dsPIC33 motor control (...)
ACS3T- 62: AC Servo motor Rated motor output: 400W Input power: single-phase 200 - 240V or 3-phase 380 - 480V, 50/60Hz Rated current 10A, peak (10sec.)20A control mode: position
Speed control of single phase induction motor of a fan. Induction motors lock onto the frequency of the mains, if the voltage is low, they slow down, take more current and finally stop. Only brush type (universal motors) can be controlled by reducing the voltage into them. (...)
Hi guys, i want to make motor RPM controller for single-phase asynchronous motor.The motor is 750W, running at 220V/50HZ.I think that power part should be with H-MOST with IGBT transistors, but i don't know how to drive gate's.Can you give some circuits? Thank's in advance!
Hiii..... first of all, one need the specification about your stepper motor....i.e. no of pole in your motor .... second micro stepping half step of full step... also you said arm processor ...which one and also you said single your stepper motor is AC or DC..... Good Luck
it is possible to control single phase induction motor and a fan(220v ac) through microcontroller . if possible, what kind of relays should i use for each of them.
As you are talking about A triac, I presume its a single phase motor. If its a universal motor with brushes then you can control the speed by this method. If its a AC only motor, then its speed is set by its number of poles and the mains frequency. Frank
Aameer, there are many types of AC motor, therefore many answers Exactly what type of AC motor do you have? single phase, three phase, split phase, capacitor start, permanent split capacitor, universal, ...

Hi, I will be starting a project which is a PID controlled single phase BLDC. I have never done motor control before. I am thinking perhaps modelling the driver though simulink is a good start. However, it has been quite a long time since I used simulink. Does anyone have any advices on how can I start (...)
The most versatile method would be to use a motor control PiC with 4 (for single phase) respectively 6 (for three phase) separate PWM outputs that can be configured as complementary outputs with deadtime. If you don't have it, the deadtime can be generated in hardware, basically by RCD circuits, delay (...)

pls send me the circuit diagram for single phase induction motor speed control using triac. i have to submit my project with in this month only.
If it is a single phase induction motor like ceiling fan motors, you can use Triac (voltage control) to control its speed. Check these
m looking to control a 1/5HP single phase motor, at rated speed it draws 3.3A so a cheep IBGT array around 50W should be up to the job. I have never seen or worked with a IGBT but they seem to just be high voltage/current transistors with a TTL input. Seems they have around 2-3V voltage drop across them while their on so (...)

Hi I'm looking for a circuit diagram of a univesal AC single phase motor speed controller that will be able to control the speed of induction motors (if it can control the speed of brushes motor as well, that would be fine but I mainly need it for use with (...)
There is big difference between running fan and running regular single phase async. motor. Asynchronous motor is very sensitive to variations in voltage and can only be regulated by means of changing frequency. Fan acts as feedback device, having low torque required at low speed and high torque at higher speed. By (...)
It should be noted, that single phase VFD may operate rather badly. It depends on the motor type. A capacitor motor will achieve nearly zero torque at low frequencies, possibly not starting at all. Also a split pole motor isn't very well suited for VF operation. Using a two phase inverter (...)
