It provides a wide range of functions for image processing, manipulation, and analysis. Objective The objective of this program is to demonstrate how to create a window with a white background using OpenCV.… Continue reading Creating a White Window Using OpenCV
Creating Larger Arrays Using np.zeros() Function in NumPy
When working with NumPy, creating arrays of specific sizes filled with zeros is a common task, especially when initializing arrays for later use. While np.array() can be used to create arrays filled with zeros, an alternative method is to utilize the np.zeros() function provided by the NumPy library. The np.zeros() Function The np.zeros() function creates… Continue reading Creating Larger Arrays Using np.zeros() Function in NumPy
Modification of array using NumPy
We have the flexibility to modify individual elements within an array without altering the entire array.. Result: Explanation: import numpy as np: This line imports the NumPy library under the alias np. frame = np.array([[0,0,0],[0,0,0],[0,0,0]]): This line creates a 3×3 NumPy array filled with zeros, just like before. frame is initialized as a 3×3 array… Continue reading Modification of array using NumPy
Representation of arrays using NumPy
A simple array can be represented by using NumPy: Result: Explanation: import numpy as np: This line imports the NumPy library and gives it the alias np. This is a common convention to make it easier to refer to NumPy functions and classes in the code. frame = np.array([[0,0,0],[0,0,0],[0,0,0]]): This line creates a 3×3 NumPy… Continue reading Representation of arrays using NumPy
Commutation in BLDC Motors
BLDC motors do not use brushes for commutation. Since the coils are static, there is no need of a mechanical commutator to energize the windings. Instead, the commutation is done electronically, usually via a microcontroller unit and semiconductor switches. Electronic commutation consists of a series of steps where current from an external drive circuitry is… Continue reading Commutation in BLDC Motors
Understanding the Functionality of a Commutator in Electric Motors
A commutator itself is a split rotary ring, typically made of copper, with each segment of the ring attached to each end of the armature coil that is used in some types of electric motors and electrical generators whose job is to periodically reverse the current direction between the rotor and the external circuit. The… Continue reading Understanding the Functionality of a Commutator in Electric Motors
