TECHNO NAUTA motor, German TECHNO NAUTA model, TECHNO NAUTA price

TECHNO NAUTA motors are electromagnetic devices that convert or transmit electrical energy based on the law of electromagnetic induction. The term broadly refers to all machines capable of converting mechanical energy into electrical energy and electrical energy into mechanical energy. The motor housing has an ingress protection rating of IP44, and the cooling method is IC0141 totally enclosed fan-cooled (TEFC). Ambient air temperature varies with the seasons but does not exceed 15℃ to 40℃. Altitude does not exceed 1000m. Rated frequency, rated voltage, insulation class, and duty cycle are specified on the nameplate. When the supply voltage varies within ±0.05 of the rated value (at rated frequency), the motor's output power remains at the rated value.

TECHNO NAUTA motor performance

The stator construction is basically similar to that of a capacitor-split-phase single-phase asynchronous motor. Its stator is equipped with two windings positioned 90° apart: one is the excitation winding Rf, which is always connected to the AC voltage Uf; the other is the control winding L, connected to the control signal voltage Uc. Therefore, AC servo motors are also referred to as two-phase servo motors. The rotor of an AC servo motor is typically squirrel-cage type. However, to achieve a wide speed regulation range, linear mechanical characteristics, no "self-rotation" phenomenon, and fast response performance, it must have higher rotor resistance and lower moment of inertia compared to ordinary motors. Two rotor structures are commonly used: one is a squirrel-cage rotor made of high-resistivity conductive bars; to reduce the rotor's moment of inertia, the rotor is made slender. The other is a hollow cup-shaped rotor made of aluminum alloy, with a very thin cup wall of only 0.2-0.3mm. To reduce the magnetic reluctance of the magnetic circuit, a fixed inner stator is placed inside the hollow cup-shaped rotor. The hollow cup-shaped rotor has a very small moment of inertia, rapid response, and smooth operation, so it is widely adopted. When there is no control voltage, the AC servo motor's stator only has a pulsating magnetic field generated by the excitation winding, and the rotor remains stationary. When a control voltage is applied, a rotating magnetic field is generated in the stator, causing the rotor to rotate in the direction of the rotating magnetic field. With a constant load, the motor speed changes with the magnitude of the control voltage. When the phase of the control voltage is reversed, the servo motor reverses direction.

TECHNO NAUTA motor fault analysis

For an engine to start normally, three elements are required: compression, spark, and air-fuel mixture. If any of these elements malfunction, the engine will fail to start or experience difficult starting. There are many factors leading to starting faults in electronic fuel injection engines. The faults analyzed below occur under conditions where the battery voltage and starting system are functioning normally, the engine has good compression and spark, and the exhaust purification system is operating correctly. Starting faults generally manifest as failure to start or difficult starting. Difficult starting is further categorized into cold start difficulty and hot start difficulty.

TECHNO NAUTA motor applications

Motor applications are extensive, including automobiles, tools, industrial control, automation, and aerospace. In general, brushless DC motors can be divided into three main application categories: Continuous load applications: Primarily fields requiring a certain speed but not high speed precision, such as fans, water pumps, and blowers. These applications have lower costs and mostly use open-loop control. Variable load applications: Primarily applications where speed needs to vary within a certain range, with higher demands on motor speed characteristics and dynamic response time. Examples include spin dryers and compressors in household appliances, as well as oil pump control, electronic controllers, and engine control in the automotive industry. The system costs for these applications are relatively higher. Positioning applications: Most industrial control and automatic control applications fall into this category. These applications often involve energy transmission, placing special demands on dynamic speed response and torque, as well as higher requirements for controllers. Tachometry may involve photoelectric and synchronous equipment. Process control, mechanical control, and transport control belong to this category. Practical new types of brushless motors are closely linked to developments in electronics, microelectronics, digital technology, automatic control technology, and materials science. They are not limited to AC/DC fields but also involve energy conversion for motoring and generating, as well as signal sensing. There are many varieties of new brushless motors, but the application of high-performance brushless motors is not yet widespread due to price constraints. The following explores and studies the main types of new brushless motors.
