Pneumatic Actuators
Valves cannot control a process by themselves. Manual valves require an operator to position them to control a process variable. Valves that must be operated remotely and automatically require special devices to move them. These devices are called actuators. … Read more

What is a Mechatronics System?
Mechatronics Mechatronics can be defined as a rapidly developing interdisciplinary field of engineering dealing with the design of products whose function relies on the integration of mechanical and electronic components coordinated by a control architecture. The primary disciplines that are … Read more

Pulse Width Modulation (PWM) Speed Control of a DC motor
We can control the speed of a motor using an open loop control or closed loop control strategy. The open loop control is the simplest form of motor control; here we simply set the drive voltage value and the motor … Read more

Key Facts about Thyristor DC Motor Drives Operation
For motors up to a few kilowatts the armature converter draws power from either a single phase or 3-phase utility supply. For large motors, 3-phase power supply is preferred because the waveforms are much smoother although traction uses single-phase with … Read more
