Detailed Description

The present invention will be described in detail with reference to the accompanying fig. 1 and the embodiments.

Referring to fig. 1, the present embodiment provides a motor structure with a resolver mounted on a flywheel, which is suitable for a flywheel integrated motor, and includes a flywheel 1, a resolver rotor 2, a motor rotor bracket 3, a rotor assembly 4, a stator assembly 5, a resolver stator fixing bracket 6, and a back cover plate 7. The motor rotor support 3 is of a hollow structure, the front end of the motor rotor support 3 is installed on one side of a friction surface of the flywheel 1, a rotary transformer installation boss is further arranged on one side of the friction surface of the flywheel 1, and the rotary transformer 2 is installed on the rotary transformer installation boss and located in the hollow position of the motor rotor support 3. And the outer wall of the motor rotor bracket 3 is sequentially provided with a rotor assembly 4 and a stator assembly 5. One end of the rotary transformer stator fixing support 6 is fixed on the rear cover plate 7, and the other end of the rotary transformer stator fixing support 6 extends into the hollow part of the motor rotor support 3 from the rear end of the motor rotor support 3.

When the motor structure of the rotary transformer of the utility model is arranged on the flywheel, the flywheel 1 is used for connecting the crankshaft of the engine. The rotary transformer rotor 2 is arranged on the rotary transformer mounting boss, the rotary transformer rotor 2 is not required to be arranged on the motor rotor bracket 3 in advance, the length of the flywheel 1 is shortened, and therefore the overall length of the motor is reduced. The motor rotor support 3 is of a hollow structure, and the installation of the rotary transformer rotor 2 is not affected. The rotor assembly 4 and the stator assembly 5 are designed according to the original design and process. The rotary transformer stator fixing bracket 6 is used for mounting a rotary transformer stator. Because the fixed bolster 6 of the rotatory change stator is fixed, consequently can guarantee the axiality of rotatory change rotor 2, can not take place the skew scheduling problem of rotatory change rotor 2, and just the fixed bolster 6 of the rotatory change stator can be cast, simple structure, and the cost is lower.
