ESC (Electronic Speed Controller) Selection for Waterproof BLDC Motor

• The speed of BLDC motor does not exceed the speed of ESC, it can be matched and used.
• Brushless DC motor speed calculation formula: battery voltage * motor KV value.
  Brushless DC motor stator speed calculation formula: motor KV value * battery voltage * motor pole pairs.
• The limit speed of V4 series ESC is 60000 ERPM.
  The limit speed of V6 series ESC is 15000 OERPM.
• If the maximum speed of BLDC motor exceeds the speed of electric speed controller, the ESC can also be matched by reducing the working voltage of motor. But we do not recommend this, because it does not really play the role of brushless DC motor.

Tips: Why Use Temperature Sensing Wire on the Waterproof BLDC Motor?

Temperature sensing line is one of the hot runner accessories, which plays an important role. General temperature sensing wire is composed of steel wire insulated with heat sensitive material. Temperature sensing wire is commonly known as "thermocouple", there are many types, hot runner thermocouple has the standard J type and K type two. But the basic principle is to use the corresponding relationship of a material to the change of temperature, through two different components of the material conductor to form a closed loop, when there is a temperature gradient at both ends. A current will flow through the loop, and there will be an electromotive force between the two ends, a thermoelectric force, which is called the "Seebeck effect".
