technical field

The invention relates to the technical field of micromotors, in particular to a multi-group comparison type micromotor load driving winding temperature experimental detection device.

Background technique

A micro motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (that is, a stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electric rotational torque. It consists of a stator and a rotor. The direction of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic field line (magnetic field direction). All kinds of energy loss (copper loss, iron loss, additional loss, etc.) are all converted into heat, causing the temperature of the micromotor winding, iron core and bearing to rise, making the micromotor rotate. When the micromotor is overloaded or poorly cooled In the state, the temperature will soon exceed the rated value. At this time, even if it will not burn out immediately, the life of the micromotor will be shortened due to accelerated aging of the insulation, and the existing maintenance and operation personnel are most likely to ignore the detection of the motor winding temperature. , it is customary to touch the temperature of the motor casing with your hand. As long as the hand sticks to it, it can be considered that the micromotor is within the allowable temperature range; The temperature of the micromotor is very high, and this test method is imprecise and inaccurate.

The vertical connectivity also reflects the horizontal force-driven and vertical and vertical force-supported connectivity effects of the connection between the above two, and again reflects the pressure synchronization and force co-movement of the connection between the two. At the same time, the shape of the connection between the above two is a three-way coordinate shape, and the three-way practical effect between the above-mentioned two is reflected in turn, and the sliding cylinder 5 is connected relatively movably through the sliding rod 7 and the installation groove, while the sliding cylinder 5 The connecting rod group 6 is fixedly connected with the other end of the synchronizing cylinder 4. The synchronizing cylinder 4, the sliding cylinder 5, the connecting rod group 6 and the sliding rod 7 constitute a driving sliding mechanism, and the driving sliding distance of the driving sliding mechanism is 0-5cm. 13 When the temperature is always maintained at a certain temperature after symmetrical observation, the controller controls the synchronous cylinder 4 to work.
