Semi-direct drive motor and linear motor direct drive motor are widely used in pumping unit. Recently, Bohai Sea equipment drilling and sales company and Daqing Equipment Company on the 2020 pumping unit drive energy-saving renovation project negotiations, successfully received 13 semi-direct-drive motor pumping unit orders. 

     It is reported that the semi-direct drive motor is a new type of special motor for oil extraction equipment. It can be directly connected to the input shaft of the reducer of the pumping unit, thus reducing the middle transmission link and further reducing energy consumption, and greatly reduce the pumping unit and motor maintenance costs, with the current oil production cost and efficiency of the need to meet. 

     As mentioned above, the new motor is a semi-direct-drive motor, and the linear motor as a "Orthodox" direct-drive Motor, is a direct conversion of electrical energy into linear motion mechanical energy, without the need for any intermediate conversion device, it also has practical application in the pumping unit. The pumping unit driven by linear motor directly uses the linear reciprocating motion of linear motor to drive the pumping rod up and down, thus achieving the goal of lifting the liquid in the oil well, when the same amount of oil is pumped in the same time, the electricity can be saved by 20%-40% . 

     The linear motor developed and produced by Kunshan Tong Mao Electronics Co. , Ltd. Adopts European and American Technical Standards and processing technology, and has good performance and high quality. At present Tong Mao makes linear motors in two major categories: U-SHAPED slot without iron core and flat plate with iron core, in addition to more than 100 kinds of marked models, but also according to customer needs Oem customization.
