He hooks up the SN754410 to two motors, giving him speed and direction control for both based on the duty cycle of a PWM signal entering the chip for less than $2.50.

Dc motor speed can be controlled smoothly down to zero, immediately followed by acceleration in the opposite direction ... and a suitable armature-voltage control system should supply power.

A standard d.c. drive system with speed and current control is shown in Figure 4.11. The primary purpose of the control system is to provide speed control, so the 'input' to the system is the speed ...

Renesas Electronics Corporation has introduced the RA2T1 microcontroller (MCU) group based on the Arm Cortex-M23 processor optimized for motor control systems. RA2T1 devices are specifically designed ...

Afterwards, you will have lessons on AC motor control components and systems, both manual and automatic. This will culminate in training for you on AC variable speed drives. Week 3 | DC Motors.

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

Part 1: The basic evolution Over the years, electric motors have been applied in an ever increasing number of applications. Think back to the replacement of steam engines with AC induction motors in ...

Brushless-dc motors are taking center stage in medical-equipment design because they last twice as long a competing technologies. • Sensorless brushless-dc-drives have evolved to a point where ...
