Description

technical field [0001] The invention relates to a motor energy efficiency measurement and detection platform, in particular to a high-voltage motor energy efficiency measurement and detection platform. Background technique [0002] High-voltage motors refer to motors with a rated voltage above 10,000V. The commonly used voltages are 6000V and 10000V. Due to the different power grids abroad, there are also voltage levels of 3300V and 6600V. The high-voltage motor is generated because the power of the motor is proportional to the product of voltage and current, so the power of the low-voltage motor increases to a certain extent (such as 300KW / 380V), and the current is limited by the allowable bearing capacity of the wire, so it is difficult to expand, or the cost is too high. It is necessary to achieve high power output by increasing the voltage. The advantages of high-voltage motors are high power and strong impact resistance; the disadvantages are large inertia and difficu...
