Embodiment Construction

[0027] Such as figure 2 As shown, the stepper motor comprehensive performance test system consists of three parts: a stepper motor operating parameter setter, six stepper motor drivers of the same specification, and six sets of motor test fixtures of the same specification; the test system can simultaneously The steering, torque, angle, current, and insulation withstand voltage performance of the six stepping motors are tested. The connection method of the three components is: the stepper motor operation parameter setting instrument sends the relevant parameters to the stepper motor driver through the power line and the signal connection line; the stepper motor driver controls the stepper motor through the electrical connection line. At the same time, the cylinder of the motor test fixture is controlled to perform corresponding work, and the steering, torque, angle, current, and insulation withstand voltage performance of the motor are tested.

[0028] Each of the six sets o...

Abstract

The invention discloses a stepping motor comprehensive performance test system. The test system is composed of three parts including one stepping motor operating parameter setting instrument, six stepping motor drivers of the same specifications, six groups of motor test fixtures of the same specifications; the test system can simultaneously test steering, moment of force, angles, current and insulating and voltage resistance performance of six stepping motors. Each group of the fixtures in the six groups of motor test fixtures is composed of a three-rod air cylinder 1, two spring clip plates2 and 4, a No.1 spring 3, two ejector rods (mounted between a motor base and the spring clip plate), the motor base 5, a No.1 coupler 6, a No.2 spring, a connection shaft 8, two bearing pedestals 7 and 9, a scale pan 10, a weight 15, a No.2 coupler 12, an angle sensor 13, a base plate, a cushion block, a weight pushing air cylinder 16 and a proximity sensor.

Description

technical field [0001] The invention belongs to the field of testing and relates to a novel comprehensive performance testing system of a stepping motor. The test system is mainly used in the production line of stepper motors to detect the rotation direction, rated output torque value, rotation angle value, drive current value, and insulation withstand voltage performance of the stepper motor. Background technique [0002] A stepper motor is an open-loop control device that converts electrical pulse signals into angular displacement or linear displacement. In the case of no overload, the speed and stop position of the stepper motor only depend on the frequency and number of pulses. It has good start-stop performance and position accuracy. It can be widely used in various automation control systems and smart home appliances. [0003] After the stepper motor is produced, it is generally necessary to measure its rated torque value. The current domestic stepper motor compreh...
