Permanent magnet integrated machine motor

Product Overview:

A permanent magnet integrated machine is a power equipment that highly integrates permanent magnet motors with related components such as drive systems.

Structural composition:

Permanent magnet motor: This is the core component, and its rotor is made of permanent magnet material, which can generate a strong magnetic field. Permanent magnets are usually made of rare earth materials and have high magnetic energy product and high coercivity, which can ensure efficient operation of motors. The stator part includes windings. When current passes through the windings, it interacts with the magnetic field of the rotor, generating electromagnetic torque and causing the motor to rotate.

Drive system: generally includes electronic components such as frequency converters and inverters, which are used to regulate and control the input current and voltage to meet the operating requirements of permanent magnet motors under different working conditions. The drive system can achieve functions such as motor speed regulation, forward and reverse rotation, start and stop, and monitor and control the operating status of the permanent magnet integrated machine. Sensors can collect real-time parameters such as motor speed, temperature, and current, and provide feedback to the controller. The controller precisely controls the drive system based on preset programs and algorithms to ensure stable and efficient operation of the motor.

Working principle: When current is input to the drive system, the drive system converts the current and voltage into a form suitable for the permanent magnet motor and delivers it to the stator winding of the motor. The rotating magnetic field generated in the stator winding interacts with the permanent magnetic field of the rotor, generating electromagnetic force that drives the rotor to rotate, thereby outputting mechanical energy. The control system monitors the operating status of the motor in real-time and adjusts the output of the drive system as needed to achieve precise control of the motor.

Performance characteristics: High efficiency and energy saving: The excitation magnetic field of the permanent magnet motor is provided by the permanent magnet, which does not require additional excitation current. Therefore, compared with traditional asynchronous motors,
Having higher efficiency and power factor, it can effectively reduce energy consumption. Especially under light and partial load conditions, the energy-saving effect is more significant. High

power density: The strong magnetic field of permanent magnet materials enables permanent magnet motors to output large power with small volume and weight. Therefore, permanent magnet drive integrated machines have high power density, which can save installation space and are suitable for occasions with high space requirements.

Wide speed regulation range: The drive system can accurately adjust the speed of the motor, enabling it to operate stably within a wide speed range and meet the speed regulation needs of different devices.

High reliability: The structure of permanent magnet motors is relatively simple, without vulnerable excitation windings and brushes, reducing the probability of faults occurring. At the same time, the integrated design makes the connections between various components tighter, and the operation more reliable with low noise and vibration: the magnetic field distribution of the permanent magnet motor is uniform, the operation is smooth, and the generated noise and vibration are small, which can provide users with a quiet working environment.
