A motor for a vacuum pump is provided to improve efficiency of the motor by filling a stator with filling material to isolate a stator coil from by-products introduced from the pump. A motor for a vacuum pump includes a stator(12) and a rotor(13). The stator is installed inside a case(11) to be wound by a coil(12a). The rotor is rotatably connected inside the stator by a shaft(14). The stator is filled with a filling material(20) to protect the coil from various by-products introduced from the vacuum pump. The filling material is epoxy resin. The motor further includes a bearing installed on one inner side surface of the case. The shaft extended from the rotor is installed in the bearing.
