AGOSTI INGRANAGGI motor Germany AGOSTI INGRANAGGI model AGOSTI INGRANAGGI price

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

AGOSTI INGRANAGGI motor advantages

The motor can be integrally mounted on the wheel axle to form an integrated direct drive system, i.e., one wheel axle is one drive unit, eliminating the need for a gearbox. Advantages of permanent magnet synchronous motors: High power efficiency and high power factor of the permanent magnet synchronous motor itself; Low heat generation of the permanent magnet synchronous motor, resulting in a simple structure, small size, and low noise of the motor cooling system; The system adopts a fully enclosed structure, with no transmission gear wear, no transmission gear noise, oil-free, and maintenance-free; The permanent magnet synchronous motor allows large overload current, significantly improving reliability; The entire transmission system is lightweight, the unsprung weight is lighter than traditional wheel axle transmissions, and the power per unit weight is high; Due to the absence of a gearbox, the bogie system can be freely designed, such as flexible bogies and single-axle bogies, greatly improving the dynamic performance of the train. Due to the use of permanent magnet material poles, especially rare earth metal permanent magnets (such as NdFeB), the magnetic energy product is high, allowing for higher air gap flux density. Therefore, at the same capacity, the motor is smaller in size and lighter in weight. The rotor has no copper loss or iron loss, and no friction loss from slip rings and brushes, resulting in high operating efficiency. Small moment of inertia, large allowable pulse torque, high acceleration, good dynamic performance, compact structure, and reliable operation.

AGOSTI INGRANAGGI motor speed control

Motor speed control: Additional resistance is connected in series to the rotor of a wound-rotor asynchronous motor, increasing the slip of the motor, causing the motor to run at a lower speed. The greater the series resistance, the lower the motor speed. This method features simple equipment and convenient control, but the slip power is consumed as heat in the resistor. It belongs to stepped speed control, with relatively soft mechanical characteristics. Voltage regulation speed control: When the stator voltage of the motor is changed, a set of different mechanical characteristic curves can be obtained, thereby achieving different speeds. Since the motor torque is proportional to the square of the voltage, the maximum torque decreases significantly, resulting in a small speed control range, making it difficult to apply to general squirrel-cage motors. To expand the speed control range, voltage regulation speed control should use squirrel-cage motors with large rotor resistance, such as torque motors specifically designed for voltage regulation speed control, or connect frequency-sensitive resistors in series with wound-rotor motors. To expand the stable operating range, feedback control should be adopted for automatic speed regulation when speed control is above 2:1. The main device for voltage regulation speed control is a power supply capable of providing voltage changes. Common voltage regulation methods include series saturated reactors, autotransformers, and thyristor voltage regulation. Thyristor voltage regulation is the best. Characteristics of voltage regulation speed control: 1, simple voltage regulation speed control circuit, easy to achieve automatic control; 2, during voltage regulation, slip power is consumed as heat in the rotor resistance, resulting in low efficiency. 3, voltage regulation speed control is generally suitable for production machinery below 100KW. Electromagnetic speed control: An electromagnetic speed control motor consists of three parts: a squirrel-cage motor, an electromagnetic slip clutch, and a DC excitation power supply (controller). The DC excitation power supply has low power, usually composed of a single-phase half-wave or full-wave thyristor rectifier. Changing the conduction angle of the thyristor can change the magnitude of the excitation current. The electromagnetic slip clutch consists of three parts: an armature, magnetic poles, and an excitation winding. The armature and the latter have no mechanical connection and can rotate freely. The armature is coaxially connected to the motor rotor, called the active part, driven by the motor; the magnetic poles are coupled to the load shaft via a coupling, called the driven part. When both the armature and magnetic poles are stationary, if DC is applied to the excitation winding, several pairs of alternating N and S poles will form along the circumference of the air gap, with magnetic flux passing through the armature. When the armature rotates with the driving motor, due to the relative motion between the armature and the magnetic poles, eddy currents are induced in the armature. These eddy currents interact with the magnetic flux to produce torque, driving the rotor with magnetic poles to rotate in the same direction, but its speed is always lower than the armature speed N1. This is a slip speed control method. By changing the DC excitation current of the slip clutch, the output torque and speed of the clutch can be changed. Characteristics of electromagnetic speed control motor speed control: 1, simple device structure and control circuit, reliable operation, convenient maintenance; 2, smooth speed control, stepless speed control; 3, no harmonic impact on the power grid; 4, large speed loss, low efficiency. 5, this method is suitable for medium and small power production machinery requiring smooth, short-term low-speed operation.

AGOSTI INGRANAGGI motor performance

Motor drive circuit, mainly considering the following performance indicators: 1, output current and voltage range. It determines the power of the motor that the circuit can drive; 2, efficiency. High efficiency not only means saving power, but also reduces the heat generation of the drive circuit. To improve circuit efficiency, start by ensuring the switching state of power devices and preventing shoot-through (a problem that may occur in H bridge circuits, where two power devices conduct simultaneously, causing a power supply short circuit); 3, impact on the control input terminal. The power circuit should have good signal isolation from its input terminal to prevent high voltage and large current from entering the main control circuit, which can be achieved using high input impedance or optocouplers; 4, impact on the power supply. Shoot-through can cause instantaneous drops in power supply voltage, causing high-frequency power supply pollution, and large currents may cause ground potential fluctuations; 5, reliability. The motor drive circuit should be as safe as possible regardless of the control signal applied or the passive load. Input signal lines are introduced through Port, pin Port1 is the motor direction signal input terminal, pin Port2 is the PWM signal input terminal, and pin Port3 is ground. Note that pin Port3 is connected to ground with a 2kΩ resistor. When the drive board and microcontroller are powered separately, this resistor provides a path for signal current return. When the drive board and microcontroller share a power supply, this resistor prevents large currents from flowing along the connection into the microcontroller motherboard ground, causing interference. In other words, it isolates the drive board ground from the microcontroller ground, achieving 'single-point grounding'. Capacitor C1 prevents sudden voltage drops caused by sudden motor startup. NAND gate U1A modulates the PWM signal and motor direction signal, converting them into square wave signals with amplitudes close to the power supply voltage.
