Advantages of Ward Leonard System
The Ward Leonard Method of Speed Control offers several advantages: The Ward Leonard Method of Speed Control offers several advantages:
- Precision Control: In true sense, main advantage is system can vary the speed of an object either faster or slower than the other objects. This is of great relevance in technology sectors such as elevators where the machine has to exercise tasks precisely at controlled speeds.
- Smooth Operation: The technology mentioned is capable to carry out the load lifting and lowering in a timely, enjoyable and effortless manner; thus, the mechanical stress and wear are lowered.
- Regenerative Braking: The system has a designed electric generator that helps improve the energy efficiency level. The energy lost during braking and acceleration is converted to electricity and then fed back to electric system.
- Reliability: The reputation of the Ward Leonard Method is relied upon for the effective operation reliability and durability. The is the reason why it is popular for the applications that require the high degree of reliability.
- Flexibility: The modular configuration of the system makes the covering of electrical motors with various power requirements possible. That has been one of the main successes that has pushed it to use in many industry sectors.
Ward Leonard Method of Speed Control
The Ward Leonard Method is a well-known (and reliable) electrical control system for controlling the speed of motors accurately. Leonard developed it in the early 20th century. Nowadays, It is widely used in various industries, particularly in applications where precise speed regulation is essential.
A system runs based on a motor-generator set and a rheostat in parallel. The main building blocks are a DC motor, a generator, and an adjustable resistor. The DC motor, i.e., the driving motor, drives the speed of the load motor by wobbling the voltage sent to it. The generator changes the electricity from the motor into DC and several variable resistors, (e.g. rheostat) or some devices adjust the current to reach the required speed.
One of the strong points of the Ward Leonard Method is the possibility of giving out precision speed control and a stable one that makes it appropriate for operations where accuracy and reliability are the most valuable. It has been applied across several industries including manufacturing, mining, and elevators, whereby its longevity can be readily seen in providing speed regulation to electrical motors.
