Efficient and stable!Engineers teach you to accurately match brushless DC motor and controller

Friend, have you been selecting brushless DC motors and controllers for your project or product recently? Do you feel a bit dizzy? Everyone knows that at first glance, we must look at power and voltage, but if it really needs to run smoothly, be usable, and be safe, just looking at these two is not enough. There are many tricks involved, so let's take a closer look today.

Don't just look at the maximum value. The key is whether it can give awesome in the working range you need. For example, if you need a lot of force to start your device, then the starting torque and low-speed torque must be sufficient. The motor also has a "natural parameter" - KV value, which is simply how much speed can be exchanged for each volt of voltage. Low KV value, usually running slowly with high power, suitable for carrying heavy loads; KV value is high, running fast but with low strength. Applications that pursue speed like it.

Next, we must pay attention to the efficiency level. High efficiency brushless DC motors not only save electricity, generate low heat, but also have a longer lifespan. The insulation level (such as B/F/H level) represents the temperature resistance of the motor, and a higher level should be selected for high temperature or heavy load applications. The protection level (IP code) is the dustproof and waterproof "armor" of the motor, and this parameter is crucial when the application environment is harsh.

When it comes to controllers, the rated current and phase current must be able to match or even slightly exceed the requirements of the motor. The control algorithm is also crucial, and a good FOC (Field Oriented Control) algorithm can make the operation extremely smooth, quiet, and efficient. The communication interfaces (such as CAN, UART, PWM) also need to be compatible with the main brain of your system.

Finally, CCC is the domestic safety standard; CE is a necessary pass to Europe, while UL is highly recognized in North America. Having these certifications means that the product has passed rigorous safety and compatibility testing, so you can use it with confidence and your customers trust it more.

So this is the key factor in choosing brushless DC motors and controllers, which determines whether they can operate stably and efficiently on your equipment for many years. Spending a few more minutes looking at these can save a lot of trouble in the future. Choose a reliable supplier: Tecote specializes in researching and producing brushless DC motors and controllers.
