Abstract

The invention discloses an electromagnetic coil with a velocity measurement function. The electromagnetic coil comprises an outer shell, a bearing base, a bearing, a coil and a coil base, wherein the bearing base, the bearing, the coil and the coil base are arranged in the outer shell; the coil is provided with an enamelled wire and two coil grooves; the electromagnetic coil also comprises a magnet, a Hall sensor and a five-core plug; three pins of the Hall sensor are respectively connected with the five-core plug through Hall sensor leads; the magnet, the Hall sensor and the Hall sensor leads are fixed with the inner wall of the outer shell into a whole through hot melt glue; an outer shell groove capable of holding a velocity measurement disc is arranged between the magnet and the Hall sensor; and cold-pressed terminals connected with two ends of the enamelled wire are arranged in the coil grooves and are also connected with the five-core plug through coil leads. The electromagnetic coil has a simple and compact structure and the velocity measurement function and is suitable for large batch production.

Description

technical field [0001] The invention relates to an electromagnetic coil, in particular to an electromagnetic coil with speed measuring function, and belongs to the technical field of automobile cooling. Background technique [0002] Since the country implemented the National III and National IV standards, energy conservation, consumption reduction, and emission reduction have become the main theme of the development of the automobile industry. As an important part of the engine cooling system, the cooling fan usually consumes 5% to 8% of the engine's energy consumption. From fixed fans, temperature-sensing ring silicon oil clutch-driven fans, to electronically controlled silicon oil clutch-driven fans, fan technology upgrades The replacement has contributed to the improvement of engine efficiency and the realization of energy saving and emission reduction. In order to achieve precise control, the electronically controlled silicone oil clutch is currently the most ideal choi...
