The present application relates to
motor control technology field, disclose a kind of three-phase asynchronous motor operation control management method and
system, comprising the following steps: step 1, the number of
encoder per revolution pulse, motor
nameplate rated speed,
acceleration time, coasting
stop time, hot permission threshold,
load shedding threshold,
tripping threshold, start-stop token upper limit and expected spin direction are determined Maximum allowable
acceleration time and minimum cooling
lock time;Step 2, according to three-phase existence state, under-
voltage state and
time condition are judged to start admission;Step 3, execute pulse accumulation and spin direction comparison to generate start determination result, and deduct start-stop token number;Step 4, during operation, based on temperature detection calculation heat index, compared with each threshold, output continue to run,
load shedding or shutdown instruction;Step 5, update heat index, when meeting unlocking condition, output unlocking result.The present application realizes the whole
process safety management of three-phase asynchronous motor from start determination, operation regulation to shutdown unlocking.
