6 D.O.L. Starting of Three-Phase Asynchronous Motors General A combination starter performs the following functions: circuit isolation and short-circuit protection, motor "ON" - "OFF" control, overload protection. The isolation and short-circuit protection functions must be performed by a fuse isolator switch, a fuse switch or a circuit-breaker. Fuse ratings recommended in this document should be used. The "ON" - "OFF" control and overload protection functions are performed by a contactor and thermal O/L relay combination. Full voltage D.O.L. starting is a simple, economic solution characterised by a high starting torque (1.9 to 2.1 times full-speed torque) and a starting current 5.5 to 7 times nominal current. I /I n C /C n 7 6 I = current; I n = nominal current C = torque; C n = nominal torque I C 1 Nominal values A1011DG Motor speed (%) 20/4 ABB Building Technologies

7 Star-Delta Starting of Three-Phase Asynchronous Motors 20 General On starting, the motor has to overcome the resistive torque and inertia of the driven machine. During this phase, current must remain within the limits acceptable by the mains. Inertia, resistive torque and mains are commonly fixed data. Although the type of starting reduces the inrush current as required, it also reduces the torque supplied by the motor. The result is a speed buildup time that varies according to the starting process used. Star-delta starting I /I n C /C n C (motor) C r (resistive torque) I = current; I n = nominal current C = torque; C n = nominal torque I (delta) I (star) Motor speed (%) C (motor) E0899DG Technical Data On starting: current inrush is reduced to a third of direct starting current, motor torque is reduced to a third of direct starting torque. High transient currents are commonly read during star-delta switching. Utilization During the initial starting phase ("star" connection), the resistive torque of the driven machine must remain, irrespective of speed, less than the "star" motor torque until "star-delta" switching occurs. This starting mode is therefore ideal for machines with no-load starting and little inertia: machine-tools, centrifugal compressors, wood working machines, etc. In order to prevent an over high current peak, at least 80% of nominal speed must be reached on "star-delta" switching. Precautions Motor nominal voltage in delta connection must be equal to that of the mains. Example: A motor for 380 V star-delta starting must be designed for 380 V in "delta" connection. Its usual designation is "380 V/660 V motor". The motor must be constructed with 6 terminal windings. Operation Starting is a three-stage process: 1st stage - "Star" connection Press the "On" button on the control circuit to close the KM2 "star" contactor. The KM1 "line" contactor then closes and the motor starts. Countdown of programmed starting time (normally 6 to 10 s) then begins. 2nd stage - "Star" to "delta" switching When the programmed starting time is up, the KM2 "star" contactor opens. 3rd stage - "Delta" connection After 50 ms have elapsed, the KM3 "delta" contactor closes, and the motor accelerates until it reaches nominal speed. Note: the 50 ms period elapsing between opening of the "star" contactor and closing of the "delta" contactor prevents arc short-circuits. ABB Building Technologies 20/5
