Burner Ventilation Motor Starter (RMS)Raadman burners ventilation motor starter raadman factory produces burners with firing range of 100 kW to 60000 kW. In burners with ventilation motor capacity of 22kW and above, the power circuit and control circuit need to be installed separately due to destructive effects of electrical noise that power circuit or high voltage has on the control devices. With Regard to this reason, raadman motor starter (RMS) in which the power circuit is embedded, is introduced by the means of this technical document. Different starting methods Star-Delta (Picture 1): A star-delta starter is the most commonly used method for starting a three-phase induction motor. In star delta starting, an induction motor is connected via a star connection throughout the starting period. In order to use this starting method, the motor must be delta connected during a normal run. This starting system has some disadvantages that are mentioned below: -Overload current drawn from electric grid at the time of starting -Current and mechanical shocks at the load torque starting moment -Current and mechanical shocks to the motor at the moment of changing status from Star to Delta which reduces the motor useful lifespan -by increasing the current range, the contactors and bimetals sizes are increased Soft Starter…
