Problems solved by technology

In ordinary DC motors, a speed measuring encoder is often used to directly measure the speed of the motor. The reliability of this speed measuring device is not very high, and it is easily disturbed. Moreover, the current speed measuring encoder needs to be directly connected to the motor shaft when used, which is easy to affect the inverter. The normal use of the motor, and the speed measuring device in the general motor can only measure the motor speed, but it lacks the function of providing timely protection for the motor and equipment. There is a gap period between the user observing that the speed is too high and turning off the motor, which is easy cause irreversible loss, in view of this, we propose a DC motor with a speed measuring device

Abstract

The invention relates to the technical field of direct current motors, in particular to a direct current motor with a speed measuring device. The direct current motor comprises a motor base and is characterized in that the motor base is fixedly connected with a shell, a rear bearing is fixedly mounted on the motor base, a rotating shaft is rotatably mounted on the rear bearing, an end cover is fixedly mounted on the shell, a front bearing is fixedly mounted on the end cover, a clamping base is fixedly installed on the rotating shaft, a blocking piece is fixedly installed on the clamping base, a lamp holder is fixedly installed on the machine shell, a laser lamp is fixedly installed on the lamp holder, a photosensitive sensor is fixedly installed on the machine shell, the photosensitive sensor is connected with a wave band converter, the wave band converter is connected with a display panel, a straight rod is fixedly connected to the rotating shaft, and a sliding groove is formed in the straight rod. The speed of the direct current motor is measured through using the laser type speed measuring structure, compared with a traditional coding speed measuring device, the rotating speed of the motor can be measured and calculated more accurately, and normal use of the motor is not affected.

Description

technical field [0001] The invention relates to the technical field of DC motors, in particular to a DC motor with a speed measuring device. Background technique [0002] DC motor is one of the commonly used motors, which can convert mechanical energy and electrical energy, and is an important basis for industrial development. In ordinary DC motors, a speed measuring encoder is often used to directly measure the speed of the motor. The reliability of this speed measuring device is not very high, and it is easily disturbed. Moreover, the current speed measuring encoder needs to be directly connected to the motor shaft when used, which is easy to affect the inverter. The normal use of the motor, and the speed measuring device in the general motor can only measure the motor speed, but it lacks the function of providing timely protection for the motor and equipment. There is a gap period between the user observing that the speed is too high and turning off the motor, which is ea...
