Many motor manufacturers offer a motor sizing tool to help with product selection, but if you don't know how to use it, you may still end up paying for it in the long run.
Welcome to Oriental Motor's "Engineering Notes" Blog:

This is a continuation of the blog post, "Technologies Used with Brushless Motors". In this section, we explain the efficiency aspect of brushless motors and compare them to AC motors.
Which type of electric motor do you size for your conveyor, XYZ table, or robot? Before you select one, you must understand the characteristics of each type of motor in the market.
Brushless motors have characteristics that make them excellent motors for speed control. In this section, we will explain the technologies that enhance the performance of these motors.
Brushless motors have different methods of controlling current flow depending on the drive system. In addition, to control the rotation speed and generated torque, it is necessary to control the amount of the motor current. Here, we will explain the PWM method for controlling the motor current.
In this post, we will explain how the two drive systems, square wave drive and sine wave drive, can affect motor torque performance.
There is a close relationship between the drive system and brushless motor characteristics, and various methods have been used to improve the controllability and characteristics of motors. In this post, we will explain two typical drive systems: square wave drive and sine wave drive.
In part 4, we will explain the main components of brushless motors: feedback, magnetic field, and permanent magnets.
In part 3, we will explain the differences in the structure and rotation principles of brushless motors, and compare them to brushed DC motors and AC motors.
This is part 2 of the Technical Manual Series for brushless motors, which explains the structure and operating principles for brushed motors for comparison. We will explain brushless motors next.
