Description

Technical Field

[0001] The utility model specifically relates to the technical field of motors, in particular to a rear-mounted motor installation structure. Background Art

[0002] An electric motor (commonly known as a "motor") is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is represented in circuits by the letter M (D in older standards). Its primary function is to generate driving torque, serving as a power source for electrical appliances and various machines. A generator is represented in circuits by the letter G. Its primary function is to convert mechanical energy into electrical energy. Currently, the most common method is to use heat energy, water energy, or other energy to propel the generator rotor to generate electricity.

[0003] In traditional motor installation, the drive shaft is often used to directly connect the drive component. However, this has great limitations when used in different modes. For example, it is inconvenient to change between the two drive modes of linear motion and rotation. For this reason, we provide a rear-mounted motor installation structure. By using a ball screw, the ball screw is an ideal product for converting rotary motion into linear motion, or vice versa. When used with a nut seat, it can also drive the workpiece to move linearly, which is more convenient to use. Secondly, the connecting seat and coupling facilitate the installation of the motor, effectively compensating for the above problems. Utility Model Content
