Problems solved by technology

Because edible oil (soybean oil, peanut oil, etc.) becomes viscous when the weather is cold, the resistance of the pump oil increases, so that the speed of the DC motor decreases, but the DC motor still rotates a fixed number of times, resulting in uneven feeding of the fluid. allow
[0003] In the scheme of the related art, in order to quantify the edible oil more accurately, it is necessary to install a position sensor (such as a Hall encoder disc, an optical encoder disc) on the DC motor to control the rotational speed. The position sensor increases the installation space of the seasoning machine. The space occupied by the seasoning machine will also increase, and the use of a position sensor will inevitably lead to an increase in cost
[0004] For the above-mentioned problems existing in related technologies, no effective solution has been found yet

Description

technical field [0001] The invention relates to the field of computers, in particular to a motor control method and device, a seasoning machine, and an automatic cooking machine. Background technique [0002] In the seasoning machine in the related art, the edible oil (or other seasoning) discharge device generally uses a DC motor to drive the pump. Because edible oil (soybean oil, peanut oil, etc.) becomes viscous when the weather is cold, the resistance of the pump oil increases, so that the speed of the DC motor decreases, but the DC motor still rotates a fixed number of times, resulting in uneven feeding of the fluid. allow. [0003] In the scheme of the related art, in order to quantify the edible oil more accurately, it is necessary to install a position sensor (such as a Hall encoder disc, an optical encoder disc) on the DC motor to control the rotational speed. The position sensor increases the installation space of the seasoning machine. The space occupied by the ...
