Do you know the classification of the working principle of the oil pump motor? It is a description of the load on the motor. It includes start-up, electric brake, no-load, break-stop and the duration and sequence of these phases. The following is explained by Dalan Motor:
The following nine categories of work are divided:
S1 continuous operation: The running time under constant load is enough to achieve thermal stability.
S2 short-time working system: running under a constant load for a given time, this time is not enough to achieve thermal stability, and then the power can be stopped for a sufficient time to make the motor cool again to within 2K of the temperature of the cooling medium.
S3 Intermittent Cycle Work: Runs on a series of identical duty cycles, each cycle consisting of a constant load run time and a break run time. The starting current of each cycle in this working system does not have a significant effect on the temperature rise.
S4 includes a start-up intermittent cycle system: operating on a series of identical duty cycles, each cycle including a start-up time that has a significant effect on temperature rise, a constant load run time, and a break-stop time.
The S5 includes an intermittent cycle of electric braking: operating in a series of identical duty cycles, each cycle including a start time, a constant load run time, a fast electric brake time, and a break run time.
S6 continuous cycle working system: It runs according to a series of identical working cycles. Each cycle includes a constant load running time and a no-load running time, but there is no stopping time.
The S7 includes a continuous cycle of electrical braking: operating in a series of identical duty cycles, each cycle including a start time, a constant load run time, and a fast electrical brake time, but no break time.
S8 consists of a continuous cycle of shifting variable loads: operating in a series of identical duty cycles, each cycle including a constant load run time at a predetermined speed, and one or more other constant load run times at different speeds , but can stop the time without interruption.
S9 load and speed non-periodic change system: Aperiodic work with varying load and speed within the allowable range. This type of work consists of frequent overloads, which can far exceed the full load.
