摘要： The invention relates to a method of controlling an electric motor integrated in a thread winding device. The inventive method consists in: using a power supply device (2) to generate a voltage or current system in order to power an assembly of windings (6-8) which are mounted on the fixed or mobile part of the motor, in such a way as to generate variable focres which, when applied the mobile part of the motor, cause said mobile part to move; using a coder (11) to generate a piece of information that is representative of the position of the mobile part of the motor in relation to the fixed part. The invention is characterised in that the voltage or current system is determined directly from the piece of information which is representative of the position of the motor's mobile part, according to a function or values that are pre-defined from the parameters of the winding device, said values or functions being independent of temporal variations in said position information.

摘要： A motor controller using an inverter (103), which is useful for preventing coasting at the time of power failure or for keeping synchronous operation of a plurality of motors (105); and which has a construction wherein a voltage (VDC) on the D.C. side of the inverter (103) is compared with a target voltage (E), a correction signal associated with the difference is added to a speed instruction from the inverter (103) and the speed of the motor (105) is smoothly reduced at the time of power failure with a voltage (VDC) on the inverter D.C. side kept at the target voltage. When applied to a spinning frame or the like, the motor controller of the present invention can prevent non-uniform winding and breakage of yarns at the time of power failure.

摘要： In the high speed driving of a ring spinning frame provided with a plurality of ring-spinning twisting-winding units (5), to compensate for the possible loss of thickness of yarn produced, when the drive speed of the spindles (5) reaches more than a predetermined rotation speed, such as 16,000 rpm in the case of spinning a cotton yarn of 40's, a total draft ratio of each drafting part (3) of the ring spinning frame is regulated to maintain the expected yarn count according to a predetermined compensation program.
