BRUSHLESS MOTOR

摘要

A brushless motor having a means for protection that protects electronic parts and the like provided on a control board from adverse effects of static a electricity and heat from a heat sink by adopting a simple mechanism is provided. By providing a protective member achieved by integrating a potential-equalizing mechanism that equalizes the potential at the heat sink with the potential at one side of a power supply line of a drive circuit provided on the control board and a thermal fuse mechanism provided on the control board, the static electricity generated at the heat sink is allowed to flow toward the circuit to minimize any increase in the electrostatic voltage and the circuit is disconnected if the temperature rises due to heat generation or the like to protect (FETs) mounted at the heat sink from high temperatures with a single member.
