At present, small household appliances have entered thousands of households in China, but due to the numerous models and brands of small household appliances, product quality varies greatly. For a long time, many small home appliances have been unable to comply with special national standards. Fortunately, the government has recognized this issue and many small home appliance industries have drafted national standards, which will unify the enterprise standards developed by various manufacturers, This is conducive to the healthy development of the small home appliance industry, and the quality of small home appliances has been put on the agenda. The production of high reliability small home appliances has become the goal of every manufacturer. Household appliances include soybean milk machine, food processing machine, juicer, mixer, meat grinder, beater, coffee machine, etc. Micro motors are very important devices in these small household appliances. How to design a highly reliable micro motor system is an important indicator for judging the quality of these small appliances. This article discusses the common problem of micro motor stalling protection in small appliances.
Introduction to LVR Series PPTC
Teconnectivity is the world's largest supplier of passive components and circuit protection devices. It is the inventor of the positive temperature coefficient resistor for PPTC polymer materials. Its overcurrent voltage protection device is widely used in many fields such as consumer electronics, communication, industry, automobiles, etc. In terms of overcurrent protection, Tyco Electronics provides PolySwitch self composite components. In terms of overvoltage protection, Taike Electronics provides GDT gas discharge tubes and PED/SESD electrostatic protection components. In addition, Tyco Electronics also offers various products such as 2pro and polyzen, MHP, RTP, and more.
Connectivity has many PPTC models available for users to choose from. The LVR series can reset circuit protection devices, which are specifically designed to prevent damage caused by overload, overheating, blockage, zero line faults, and other potential factors used in commercial and household appliances. When the micro motor is working normally, the initial small resistance value of PPTC will not affect the operation of the micro motor. When PPTC is overloaded or locked, the resistance will rapidly increase to reduce the overload current and protect the micro motor. After troubleshooting, PPTC can restore normal resistance and enable the micro motor to operate normally. The Connectivity LVR series products include various products with rated voltage of 120 VAC and 240VAC line voltage. These products have low impedance, fast operation time, compact size, and can be reset, which helps circuit designers to launch safe and reliable products and reduce maintenance costs during the warranty period.
