There are four primary types of motor control methods for induction motors connected to VFDs: V/f (volts-per-hertz), V/f with encoder, open-loop vector, and closed-loop vector. The 0208AAA model, on the other hand, uses up to 208 A during normal duty cycles, handles 150 hp, and weighs 218 lb. The 0004FAA modelГўВЂВ™s normal duty current load is 4.1 A, it handles up to 2 hp motors, and weighs 9 lb.

Both are in the companyГўВЂВ™s A1000 Series of drives and are powered by three-phase 380 to 480 V. Variable frequency drives come in all sizes, as these two VFDs from Yaskawa America Inc. The control methods this article focuses on are perhaps more accurately called motor-control methods. Such 2- and 3-wire setups determine whether a VFDвЂ™s input-control terminals interface with maintained contacts or momentary push buttons to start and stop the drive. Many people in the industry think control methods are the sequencing methods that control VFDs, as in 2- and 3-wire setups. Once engineers and designers understand the advantages, disadvantages, and particular specifications for each control method, choosing the right one for any application becomes simple. Efficiently run motors also use less energy and experience less downtime for greater overall savings.ДЇor motors controlled by a variable frequency drive (VFD), the control method used in large part determines a motorвЂ™s efficiency and performance in an application. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall performance. They can be used in different robots having wheels and robotic cars to move in different directions.Motors account for at least half of the energy consumed in the U.S. There are several applications of DC motors. dc motor interfacing with atmega32 microcontroller simulation

To observe the functionality of the circuit according to given code, dump the HEX file of the code in circuit and see the simulation results. The code will execute infinite times due to while loop.

For anticlockwise direction set PB.3 & PB.1 high. First motor will rotate in clockwise direction by setting PB.0 & PB.2 high for 3 seconds and then both motors stops for one second by setting all four pins to low. PORTB = 0x0A //motor rotation in anticlockwise directionДЄs motors are connected to first four pins of PORTB thatвЂ™s why we make the direction of PORTB as output by using command (DDRB). PORTB = 0x05 // motor rotation in clockwise direction

#define F_CPU 16000000UL // 16 MHz clock speedДDRB= 0xFF // direction of port B as output We use Atmel studio 6 for coding and the code was developed in C language. TRUTH TABLE MOTOR A MOTOR B DESCRIPTION 0 0 Both Motors stop 0 1 Motors move in anticlockwise direction 1 0 Motors move in clockwise direction 1 1 Both Motors stop The below truth table will help you to develop understandings with the basic movements of motors for building a code.

Set the frequency of crystal and Atmega32 to 16MHz.

Connect the VCC with 12V and GND pins of L293 with ground.

Pin EN1 & EN2 pins of L293 are connected to 5V.

Connect the IN1, IN2, IN3 & IN4 pins of L293 with PB0, PB1, PB2 & PB3 pins of Atmega32.

To make the circuit on proteus, select Atmega32, L293 IC, crystal, DC motor and rest of the components from built-in library. The circuit on proteus is shown in the figure given below: dc motor speed control circuit diagram Pin EN1 & EN2 are PWM pins while IN1, IN2, IN3 & IN4 are used to provide signals to the motors. It is a16 pin IC in which pins out1, out2, out3 and out4 are connected to two motors. H-bridge is a motor driving unit used to control the direction of two motors at a time either clockwise or anticlockwise direction. L293 is a most popular and less expensive built-in H-bridge in a small integrated circuit used for low current motors. This article will surely helps you in controlling two motors at a time with the help of L293.
