When the motor is started, it needs to overcome its own inertia and the reaction force of the load at the same time, so the motor needs a large current and torque when it starts. Connect the PTC thermistor in series with the starting auxiliary coil. After starting, the PTC thermistor enters a high-impedance state and cuts off the auxiliary coil, which can exactly achieve this effect.
· Few domestic advanced manufacturing companies with NTC chip (0.6mm packaging technology) design capabilities
· There are very few domestic full-size automatic single-end glass sealing machines and single-end thermistor testing machines
· Domestic exclusive dual temperature point (B value) diode-type thermistor tester, achieving 0.3% accuracy for medical and military use
· 5 invention patents, 100 utility models, 2 reserved technologies
