摘要
In order to achieve the energy efficiency class IE4 defined in IEC standard 60034, it is necessary to operate permanent-magnet synchronous machines directly from the supply system. Since this is not readily possible, soft-starting devices come into consideration as cost-effective solutions. The problem of transmitter-free running up can be split into two component problems: determining the initial rotor angle and running up the machine. The present invention describes a (rotary) transmitter-free starting method with which the motor can be started using a soft-starting device.
