2. Shorting PMSM stator
Shorting PMSM stator means shorting phases UVW of the PMSM, which produces
resistance to restrict movement of the elevator car.
In field application, an auxiliary NC contact is usually added to the NO contact of the output
contactor to short PMSM UVW phases to achieve the effect. It is feasible in theory but may
cause over-current actually.
