Problems solved by technology

For this reason, it is necessary to consider adding a speed measuring device when designing the motor structure. The speed measuring device makes the motor structure complex and bloated
In addition, due to the low reliability and high failure rate of the speed measuring device attached to the motor, the motor cannot work reliably. When the speed measuring device fails, the vehicle system cannot work normally. When replacing the speed measuring device, the motor must be removed, which delays the normal operation of the vehicle. Increased system maintenance costs and maintenance costs. Whether the entire vehicle system can work reliably depends on the reliability of the speed measurement device. Due to the high reliability of the motor itself, there are fewer failures. If the reliability of the speed measurement device is improved, the reliability of the vehicle system will be greatly improved.

Abstract

The invention provides a high-reliability speed measuring type double-way speed measuring structure of a motor, and aims at solving the problems of low reliability and high fault rate of the speed measuring devices of the existing motors. The high-reliability speed measuring type double-way speed measuring structure of the motor comprises a speed measuring gear, a mounting cover, a speed sensor and a speed measuring coder; the speed measuring gear is fixed on a motor rotating shaft, and an axis of the speed measuring gear outwards extends to be equipped with a speed measuring shaft; the mounting cover is mounted on a motor end cover; the speed measuring sensor and the speed measuring coder are both mounted and fixed on the sidewall of the mounting cover; the speed measuring sensor is used for detecting the rotating number of the speed measuring gear as well as the rotating speed of the speed measuring shaft. According to the high-reliability speed measuring type double-way speed measuring structure of the motor, the double-way speed measuring is adopted, so that the working reliability of a system can be greatly improved, and the maintaining time and the maintaining cost can be greatly reduced; the unique design structure reduces the motor space, lowers down the cost and achieves the double-way speed measuring function.

Description

technical field [0001] The invention relates to a motor speed measurement device, in particular to a dual-channel speed measurement structure for high reliability speed measurement of a motor. Background technique [0002] When the motor is used as a traction power supply device to drive the vehicle system to run, it needs to provide real-time speed to the vehicle control system. For this reason, it is necessary to consider adding a rotational speed measuring device when designing the motor structure, which makes the motor structure complex and bloated. In addition, due to the low reliability and high failure rate of the speed measuring device attached to the motor, the motor cannot work reliably. When the speed measuring device fails, the vehicle system cannot work normally. When replacing the speed measuring device, the motor must be removed, which delays the normal operation of the vehicle. Increased system maintenance costs and maintenance costs. Whether the entire vehi...
