When the forward or reverse rotation turns of the motor are completed within a specified time, the motor stops running; when the number of forward or reverse rotation turns of the motor exceeds the set time, stopping the motor according to the preset forward or reverse running time of the motor; the invention takes the number of the rotation turns of the motor as the main part and the running time of the motor as the auxiliary part, so that the motor can stop running at the latest at the preset running time, the damage of the motor is prevented, and the service life of the rocking massage chair is prolonged.

Further, the step S1 further includes: s11, when the forward rotation time of the motor reaches the set forward operation time T1 and the number of forward rotation turns of the motor is lower than the preset threshold value, judging that the motor is locked, immediately alarming and controlling the motor to brake emergently, otherwise, entering S2.

Further, the step S3 further includes: s31, when the reverse rotation time of the motor reaches the set forward operation time T3 and the number of reverse rotation turns of the motor is lower than the preset threshold value, judging that the motor is locked, immediately alarming and controlling the motor to brake emergently, otherwise, entering S4.

Further, the step S1 is preceded by preset operation parameters including a motor operation time, a motor rotation number and a motor stop time. In the present embodiment, the motor operation time includes motor forward and reverse operation times; the number of the motor rotation turns comprises the number of the motor forward rotation turns and the motor reverse rotation turns; the motor stop time includes that the motor forward and reverse stop time are the same.

In the embodiment, the forward running time T1 of the motor or the reverse running time T3 of the motor and the number of turns are the same, and the motor can be stopped after the forward running time T1 or the reverse running time T3 of the motor and the number of turns are reached; under normal conditions, the number of motor rotation turns reaches the standard first, and the motor stops running (namely, the number of motor rotation turns is taken as the main, and the running time of the motor is taken as the auxiliary); in an abnormal condition, that is, in a specified time, the number of revolutions of the motor is not reached or the motor is locked, the forward running time T1 or the reverse running time T3 of the motor is reached first, and the motor stops running. The motor forward running time T1 or the motor reverse running time T3, the time for the motor to rotate forwards for the set rotation number is T2 when idling, and the time for the motor to rotate reversely for the set rotation number is T4 when idling; defining the actual time required by the forward rotation number and the reverse rotation number of the motor as T5 and T6; therefore, when the user sits on the massage armchair and the motor normally runs, T1 is more than or equal to T5 and more than T2 or T3 is more than or equal to T6 and more than T4, the motor stops running at T5 or T6; when the rotating speed of the motor is too slow or the motor is blocked, namely when T5 is more than T1 is more than T2 or T6 is more than T3 is more than T4, the motor can stop running at the latest at T1 or T3, the motor is protected, the motor is prevented from being burnt out, and the service life of the motor is prolonged.

Furthermore, T1 is T2+0.5 s-T2 +1 s.

Furthermore, T3 is T4+0.5 s-T4 +1 s.

Further, T1 equals T3.

Further, the motor stop time is 0.5s-1.5 s.
