Self-starting single-phase synchronous motor |
摘要 |
A self-starting single-phase synchronous motor without an auxiliary coil comprises a diametrically magnetized permanent-magnet rotor and a two-pole stator provided with exciter coils. A PTC resistor (5) is arranged in the circuit (1) of the exciter coils. The PTC resistor is proportioned so that its resistance will increase to a continuously permissible load resistance value after approximately 0.5 to 1 sec.
