Abstract
The invention relates to a motor which comprises a drive system which has a stator (10) and a rotor (14), and a control system which controls the drive system and has circuit boards (21), (22), both being housed in a casing (2), wherein the casing (2) has a first conductive pin (25) for flowing a current to input power to the control system and a second conductive pin (26) for flowing a current to output from the control system to respective phases of a coil, and the circuit boards are supported by the first and second conductive pins. And, the invention relates to a method of manufacturing a motor which comprises the steps of using a first die (101) and a second die (102) which are mutually connected with a die split face (104) therebetween and a third die (103) which is inserted in the middle of the first and second dies, inserting and fixing a motor stator, a metallic cylinder and embedding members into a cavity formed by the first, second and third dies, and pouring a molten resin to effect resin molding.
