摘要
A procedure for determining the parameters for an electric drive controlling a synchronous elevator motor with permanent magnets, a computer controlling the operation of the electric drive being provided with a control model describing the elevator and containing settable parameters. The elevator car installed in the elevator shaft is allowed to enter a motional condition produced by the balance difference between the elevator masses; using two different loads connected to the terminals of the synchronous motor, the rotational speed, electromotive force and synchronous reactance of the synchronous motor are measured while the elevator car is in a constant motional condition, and the stator resistance is measured via a separate measurement; and a control model describing the elevator is computed and formed from these measurements.
