The embodiment of the invention discloses storage equipment, a data writing method thereof and motor equipment. The storage equipment comprises a memory and a processor, the memory comprises a plurality of physical pages, each physical page comprises a control information unit and a plurality of data units, and the control information unit stores writing data unit information; and the processor is electrically connected with the memory, and is used for determining a first physical page for executing the write operation last time during the write operation, determining a to-be-written data unit according to the written data unit information stored in the control information unit in the first physical page, and then executing the write operation. In the embodiment of the invention, the to-be-written data unit is determined by controlling the written data unit information stored in the information unit, so that sequential storage is realized, and the read-write service life of the memory can be prolonged.
Description
Technical field [0001] Embodiments of the present invention relates to memory technology, in particular to a storage device and a data writing method thereof and a motor device. Background [0002] In stepper motor drive products, the product needs to be initialized each time it is powered on to determine the zero position of the running stroke of the product. Specifically, the zero point calibration is carried out by means of an electronic ball valve in a stepper motor. Electronic ball valve initialization before stopping at the non-full-off position, the electronic ball valve fully closed direction to set a limited position frame, in the process of performing initialization, the electronic ball valve to the full-off direction of action and by multiple times hit the limit frame that is, the collision end, to ensure that the electronic ball valve must be in the full-off position, to complete the initialization. [0003] The initialized crash action affects the product operating l...
