Embodiment approach 1
[0031] A motor control method, comprising the steps of:
[0032] S1 Determine the rated acceleration change value δ: determine the acceleration change curve of the motor according to the optimal working curve of the motor, and take the maximum value in the acceleration change curve as the rated acceleration change value δ;
[0033] S2 controls the motor: controls the motor to rotate and work within the range less than the rated acceleration change value δ.
[0034] In the above motor control method, the optimal working curve of the motor can fully reflect the performance of starting, accelerating, running, decelerating and stopping the motor. Take the maximum value in the acceleration change curve as the rated acceleration change value δ, and control the motor to rotate and work within the range less than the rated acceleration change value δ, so that the performance of the motor can be fully utilized, and the reliability of the load connected to the motor can be improved. st...
Embodiment approach 2
[0037] A turntable control method for a turntable that can be rotated arbitrarily, comprising the following steps:
[0038] S10a determines the turning direction of the turntable: setting the initial position A of the turntable 0 , Set the end position A of the turntable 1 , take the turntable from the initial position A 0 to end position A 1 The direction with the smallest rotation angle is the rotation direction of the turntable;
[0039] S20a Drive the turntable to rotate: use the motor control method described in Embodiment 1 to drive the motor connected to the turntable to work.
[0040] In the above-mentioned control method of the turntable, the turning direction of the turntable is determined through S10a, so that from the initial position A 0 Go to end position A 1 The minimum path, which can reduce the energy consumption of the motor. At the same time, since the S20a uses a motor control method to drive the turntable to rotate, it can make the turntable rotate r...
Embodiment approach 3
[0043] combine image 3 As shown, an embodiment provides a turntable control method for a turntable with limited rotation, including the following steps:
[0044] S10b sets the initial position of the turntable: confirm that the turntable is at the first limit position B 1 and the second extreme position B 2 Rotate between, set the turntable from the first extreme position B 1 to the second extreme position B 2 The position between is the initial position B of the turntable 0 ;
[0045] S20b drives the turntable to rotate: set the end position B of the turntable 3 , using the motor control method described in Embodiment 1 to drive the motor connected to the turntable from the initial position B of the turntable to 0 Go to end position B 3 .
[0046] The above turntable control method, the initial position B 0 Set at the first extreme position B 1 to the second extreme position B 2 between, able to shorten the turntable from the initial position B 0 Go to the first ...
