Tips: Physical concept of aluminum wire wound resistor.

Like other resistors, aluminum wire wound resistor in physics indicates the resistance magnitude of conductor to current flow. Resistance will cause the change of electron flux. The smaller the resistance, the greater the electron flux, and vice versa. For aluminum wire wound resistor, the resistance value is generally related to temperature, material, length and cross-sectional area. Temperature coefficient is a physical quantity to measure the influence of temperature on aluminum resistor. It is defined as the percentage change in resistance value for each 1℃ increase in temperature.

Aluminum wire wound resistors protect the machine from voltage rises in the DC bus. At the same time, the reduction in current causes engine to reduce speed, helps to brake the machine.
