  • Publication number: 20220247275
    Abstract: Increase the heat dissipation effect of the heat sink on the heat generating element. In the rotary electric machine, the portions of the circuit board that are installed in the first and the second installation portion of the heat-sink are configured as non-coated portions, and the non-coated portion is not coated with resist. Therefore, the circuit board can be installed in the first and the second installation portion of the heat-sink without being affected by the variation in the film thickness of the resist. Thus, the gap between the FET mounted on the circuit board and the first to third heat dissipating portion of the heat-sink can be set as small as possible. Therefore, the heat generated by the FET can be efficiently transferred to the heat-sink. As described above, the heat dissipation effect of the heat-sink on the FET can be enhanced.
