BAUER motor Germany BAUER model BAUER price

BAUER motor refers to a motor that can operate on both DC and AC power supplies. This type of electric motor is widely used in household appliances, manual devices, computing tools, and precision machinery. In addition, it is frequently used in medical equipment, communication technology, measurement technology, the film industry, and many other fields.

BAUER motor working principle

The electromagnetic switch of the motor mainly consists of an electromagnet mechanism and a motor switch. The electromagnet mechanism comprises a fixed core, a movable core, an attraction coil, and a holding coil. The fixed core remains stationary, while the movable core can move axially within the copper sleeve. A push rod is fixed to the front end of the movable core, and a switch contact disc is installed at the front end of the push rod. The rear section of the movable core is connected to a shift fork via adjusting screws and connecting pins. A return spring is installed outside the copper sleeve to reset the movable core and other movable components. When the magnetic flux generated by the attraction coil and the holding coil has the same direction, their electromagnetic forces superimpose, attracting the movable core forward until the contact disc at the front end of the push rod connects the electric switch contacts, thereby closing the main motor circuit. When the magnetic flux generated by the attraction coil and the holding coil has opposite directions, their electromagnetic forces cancel each other out. Under the action of the return spring, the movable core and other movable components automatically reset, the contact disc disconnects from the contacts, and the main motor circuit opens.

BAUER motor fault analysis

Motor injector faults generally manifest as: injector nozzles clogged by gummy substances, carbon buildup, or poor sealing causing dripping, leading to mixture concentration being too low or too high. The detection method is: first, start the engine and use a stethoscope to check the operating sound at each injector. If no sound is heard, check the wiring connector, the injector, or the injection signal from ECU; then, use a multimeter to measure the resistance between the injector terminals. If the resistance value does not match the specified value, replace the injector; finally, check the injector fuel volume, which should be within the normal range, and the difference in fuel volume between cylinders should be less than 5cm3. The water temperature sensor is used to detect the cooling water temperature and convert it into a voltage signal related to the temperature, inputting it to ECU as the basis for ECU to correct the fuel injection volume. If the water temperature sensor fails, or if there is an open circuit, short circuit, or severe scale buildup in the wiring between the sensor and ECU, it will cause significant deviation in the output signal, ultimately preventing the injector from increasing or decreasing the fuel volume in time, leading to starting difficulties. Most electronic fuel injection engines use a stepper motor-type idle speed control valve. ECU adjusts the energization sequence of the stepper motor's electromagnetic coils based on the engine's operating conditions, causing the conical valve body on the stepper motor shaft to screw in or out, adjusting the opening of the bypass air passage to regulate the bypass intake air volume. If the engine is difficult to start but starts with slight throttle application, it indicates a fault in the idle speed control valve. Disassembling the ISC valve will reveal significant carbon buildup, gummy deposits, and oil accumulation on the conical surface of the valve body, reducing the adjustable range of the conical valve. This results in reduced intake air volume and an overly rich mixture during cold starts, causing starting difficulties.

BAUER motor speed control

Motor speed control: A hydraulic coupling is a hydraulic transmission device, generally consisting of a pump wheel and a turbine, collectively referred to as working wheels, housed in a sealed casing. A certain amount of working fluid is filled into the casing. When the pump wheel rotates driven by the prime mover, the fluid inside is pushed by the blades to rotate. Under the action of centrifugal force, the fluid enters the turbine along the outer ring of the pump wheel, exerting thrust on the turbine blades in the same rotational direction, thereby driving the production machinery. The power transmission capacity of the hydraulic coupling is consistent with the relative filling volume of the fluid in the casing. During operation, changing the filling rate changes the turbine speed of the coupling, achieving stepless speed regulation. Its characteristics are: 1, wide power adaptation range, meeting the needs of different powers from tens of kilowatts to thousands of kilowatts; 2, simple structure, reliable operation, convenient use and maintenance, and low cost; 3, small size, large capacity; 4, convenient control and adjustment, easy to achieve automatic control. 5, this method is suitable for speed control of fans and water pumps. Variable frequency speed control range: 5-100 Hz stepless speed control. Below 50 Hz (60 Hz) is constant torque speed control; above 50 Hz (60 Hz) is constant power speed control. *Voltage boost through the variable frequency device ensures that the motor outputs rated torque at 5 Hz without burning out due to overheating. *Smooth torque at low speeds, no crawling phenomenon. *The motor can withstand 160% overload of rated torque for 1 minutes. Equipped with a gear transmission motor (friction wheel) with variable transmission ratio.
