At present, my country has become a big country in the production of dynamometers, but it still faces some problems in the promotion and application of high-efficiency dynamometers. Therefore, the dynamometer industry should seize the development opportunities and take innovation-driven, intelligent transformation, strengthening of the foundation, and green development as the guiding ideology to realize the dynamometer industry from big to strong as soon as possible. Dynamometers must be used wherever electrical energy is converted into mechanical energy or mechanical energy is converted into electrical energy. Therefore, the dynamometer industry as a whole has a huge market capacity.
