How to Calculate Motor Winding Data

When it comes to calculating power loss in a Brushless DC (BLDC) drive, there are various factors to consider. As a newcomer to electronics, it can be overwhelming to navigate through complex formulas and terminology. In this article, we will explore the basics of BLDC drives, including power loss calculation, efficiency maps, and winding data.

The Need for Power Loss Calculation

In a BLDC drive, the power loss calculation is crucial in determining the motor's efficiency and performance. The question remains: how do you calculate power loss in a BLDC drive? This calculation involves understanding the internal resistance of the motor, magnetic losses, and winding losses.

Tutorials and Manuals for Power Loss Calculation

If you are new to electronics, finding a suitable tutorial or manual for calculating power loss in a BLDC drive can be challenging. There are various resources available online, but they may not cater to your level of expertise. In this article, we will explore some of the key concepts and formulas involved in power loss calculation.

Efficiency Maps for BLDC Drives

One way to validate your calculations is by comparing them with experimental data. However, finding efficiency maps for BLDC drives can be difficult. Texas Instruments provides a manual for calculating power loss in their drive systems, but it may not be easily accessible or understandable for beginners.

Torque Constant and Winding Data

When calculating power loss in a BLDC drive, the torque constant (Kt) is an important parameter. However, it needs to be recalculated taking into account temperature changes and magnetic losses. This formula, Ktwarm = kt * (1 + magnet_temp_coeff * temp_difference), may seem similar to the heated resistor formula.

Motor Calculations for Coreless Brush DC Motors

To calculate power loss in a BLDC drive, you can use thermal equivalent circuits and iterate through calculations to determine new coil temperatures. This process involves understanding the motor's internal resistance, magnetic losses, and winding losses.
