Electric motors that have found wide application in various sectors of industry Have unique features such as high reliability, high efficiency, quick acceleration and have small sizes. Brushless DC motors meet these requirements well. In this study, the design of a brushless DC motor speed limits for the particular application at 1800 rpm that can be equivalent to 140 watts output was provided....

To promote energy saving, we developed a high efficiency brushless DC motor with a new manufacturing method of a stator for compressors. This motor consists of a concentrated winding stator and an interior permanent magnet rotor. The stator has the core structure that we call “a joint-lapped core”. The joint-lapped core is able to open and bend in reverse. While winding the coil, the joint-lapp...

This paper presents a sensorless drive technique for permanent-magnet brushless DC motors applied to electric propulsors of small ships or underwater vehicles. Propulsors enveloping electric motors (e.g., POD or subsea thrusters) have been increasingly applied due to their advantages of excellent maneuverability, high efficiency and low maintenance costs. To secure reliable operation under wate...

This paper presents digital speed control of permanent magnet brushless dc motor using TMS320F2812 DSP controller. The DSP controller used here has the special features for digital motor control. Control algorithms used for the speed control has been implemented by assembly language programming in TMS320F2812 DSP controller. According to the input command, feedback and the control algorithm, th...

This paper presents the analysis, design and implementation of cost effective sensorless control scheme of Brushless DC Motors (BLDCM). There are several methods proposed in BLDC motor drives to obtain optimum current and torque control with minimum torque pulsation. But while coming to industrial applications, BLDC motor voltage contains harmonics which are caused because of high speed switchi...
