Porównanie silnika indukcyjnego oraz synchronicznego z magnesami trwałymi i rozruchem bezpośrednim - badania eksperymentalne

In this paper parameters of line start permanent magnet synchronous motor and induction motor are compared. On the basis of standard 2 HP induction motor an interior LSPMSM was successfully designed and built. The measurements were conducted at steady state and during dynamic performance. The impact of load level on starting properties was investigated. The torque, speed and stator current transient were measured during motor's start up. Full load characteristic of current, power factor and efficiency is also presented. The measurements confirmed that using permanent magnets increases power, efficiency and power factor of the motor.
