But the lanes are protected from motor vehicles by a line of white paint-a largely metaphorical barrier that many drivers ignore and police do not vigorously enforce.
Motor and inverter can be protected by the current cut-off negative feedback when motor is overload or locked-rotor.
当电机负载过载或堵转时，采用电流截止负反馈环节可保护电机和驱动器；

The utility model can cause that the power of a motor is cut off automatically, when the power of one phase of the three phase motor is cut off; therefore, windings are protected.
