Abstract

The present application discloses a phase detecting method and device, a computer device, and a computer readable storage medium. The method comprises the steps of: obtaining a Hall signal value inducted by a Hall sensor in a three-phase motor, and obtaining a counter electromotive force value of a set A phase relative to a set B phase in the three-phase motor when the current Hall signal value isjumped to an adjacent Hall signal value each time, wherein the counter electromotive force value is detected and obtained when the three-phase motor is in a rotation state under the drive of the external force; and according to the corresponding counter electromotive force value when the current Hall signal value is jumped to the adjacent Hall signal value each time, calculating an electrical angle value corresponding each counter electromotive force value so as to obtain a corresponding relation of A, B and C phases, the Hall signal value of each jump and each electrical angle value. The technical problem is solved that the detection result of the phase detection method large in error in the prior art.

Description

technical field [0001] The present application relates to the technical field of motor phase sequence detection, in particular, to a phase detection method and device, computer equipment, and a computer-readable storage medium. Background technique [0002] During the assembly process of the three-phase motor and the driver, it is necessary to connect the U, V, and W three-phase power lines of the driver to the A, B, and C three-phase power lines of the three-phase motor. If you do not know how to connect the driver and the three-phase motor, or if the phase sequence mark of the three-phase motor is unclear or the phase sequence mark is missing, starting the three-phase motor with random wiring may cause damage to the drive or the three-phase motor, and in severe cases may cause Accidents have serious consequences. [0003] At present, there are many phase detection methods for brushless DC three-phase motors, some of which are realized by software, but the complexity of th...
