<p>The spindle (4) has a stator with three motor coils, and a power supply provided with three electrical phases. The stator has six free junctions for electrically conducting connections of motor coil origins (U1, V1, W1) and motor coil ends (U2, V2, W2) of the motor coils to the three phases. The junctions are formed in a delta connection mode of the coils as six free individual cable junctions. Connecting devices (5, 6) electrically conduct connection of the three individual cable junctions such that a star connection mode of the motor coils is achievable.</p> |
