A plurality of spindles of a textile machine are all mechanically interconnected and individually grouped, the individual groups of the spindles are driven by respective polyphase electric motors having respective feed lines all connected in parallel to the output lines of a polyphase electric power supply. Either the current or the voltage of the supply is maintained generally constant independent of load and a characteristic of the electricity in the feed lines of only one of the motors is monitored in the constant-current system or in the output lines of the supply in the constant-voltage system. An alarm, for example an optical or acoustic signal or just an indication on a display or printout, is generated when the characteristic of the electricity in any one of the monitored lines varies substantially from that of the other monitored lines.
