The new Downhole motor from China manufacturer drive circuit belongs to the field of drive control of downhole logging instruments for oil, gas and water wells and various intelligent downhole tool motors. The circuit of the present invention is an H-type circuit, including a logic control circuit and a double-bridge conduction Circuit, wherein the logic control circuit includes a forward rotation control circuit and a reverse control circuit, the double bridge conduction circuit includes an A bridge drive output circuit and a B bridge drive output circuit, and the motor is driven by the A bridge output circuit or by the B bridge. The bridge circuit drives the output circuit to drive; by applying different negative working voltages, the motor is turned forward, reversed or stopped, thereby controlling the opening and closing of the current collecting umbrella. The circuit of the present invention does not require contact switching, and can perform multi-parameter measurement. Well, the power supply voltage range is wide, the operation is simple, and the work is reliable. It can provide higher working voltage and larger driving current for the motor in high temperature environment. It is suitable for oil, gas, water well downhole logging tools and various intelligent downhole Drive control of tool motors.

The above is a brief introduction to the relevant knowledge of the new Downhole motor from China manufacturer drive circuit.
