The direction of the motor is controlled by the polarity of the PWM signal. When the PWM signal is positive, the motor will rotate in one direction. When the PWM signal is negative, the motor will rotate inthe opposite direction. PWM control is a very efficient way to control the speed ...

Controller for PWM/PAM motor, air conditioner, and method of motor control In a motor driving unit controlled by switching to/from PWM control from/to PAM control so that the maximum limit of motor speed can be increased and, at the same time, the unit can be operated at maximum efficienc...
L6258EX PWM controlled high current DMOS universal motor driver Features ■ Able to drive both windings of a bipolar stepper motor or two DC motors ■ Output current up to 1.5A each winding ■ Wide voltage range: 12V to 40V ■ Four quadrant current control, ideal for microstepping and DC...
If you set the PWM reference voltage to 2.5 V, the motor runs at approximately 2000 rpm. To achieve fast simulation, this example sets the Simulation mode parameter of the Controlled PWM Voltage and H-Bridge blocks to Averaged. To validate the averaged behavior, set the Simulation mode ...

The motor to be controlled is fed by a DC source through a chopper. The tachogenerator senses the speed, which gives voltage as output. And this voltage is fed to the microcontroller to drive the speed of the motor. The output voltage of tachogenerator is provided to the microcontroller and...
9/5/2014 EMC_Brushless_and_Stepper_Motors Roger Enns 1 DC Motor PWM Speed Control • Previous methods of speed control used resistors to drop current/voltage in either the armature or the field. This results in a loss of electrical energy through the control resistor. • An electronic alt...
