Key Features

How the PTC Motor Starter Works

The Motor PTC Thermistor plays a crucial role in Motors circuits. Once the motor starts, the thermistor switches to a high resistance state, cutting off the starting circuit and preventing overheating. For optimal performance, the PTC Thermistors Motor Starters must cool down and return to its original state before restarting. This ensures effective PTC Thermistors Motor Starter and prevents damage to the motors or compressors.

Working Principle

The PTC Motor Starter works by leveraging the Motor PTC Thermistors properties. When voltage is applied, a high current flows through the PTC element. As the temperature rises, the resistance increases sharply, reducing the current flow. This process, lasting from 0.1 seconds to several seconds, depends on the heating capacity, and operating voltage.

Temperature Recovery and Safety Considerations

Once the voltage is removed, the Motor Winding Protection PTC Thermistors cools and returns to its low resistance state. This recovery is critical for safe operation in refrigerators and air conditioners. Sufficient cooling time is essential before restarting the motor, as repeated quick operations may prevent proper current flow, risking compressor burnout.

Starting the Electric Motor with PTC Element

To start an electric motor, high torque is needed to overcome inertia and load resistance. The Motor PTC Thermistor provides the necessary heavy current for start-up. After starting, it transitions to a high resistance state, breaking the starting circuit. This allows the motor to run efficiently, ensuring long-lasting PTC Motor Starter.
