Permanent Magnet Motor

The PM motor uses permanent magnets to generate the motor's magnetic field. It does not require an excitation coil or excitation current.

Compared with the traditional electric excitation motor, it has significant advantages such as high efficiency and simple structure.

The application range of permanent magnet motors is extremely wide, covering almost all areas of aerospace, national defense, industrial and agricultural production and daily life.

With the development of high-performance permanent magnet materials and the rapid development of control technology, the application of permanent magnet motors will become more extensive.

Permanent Magnet DC Motor

The working principle and structure of permanent magnet DC motors are similar to ordinary DC motors, the difference is that permanent magnet poles are used instead of current-excited poles.

The commutation methods can be divided into brush motors and brushless motors. Electronic commutation.

Breakdown

The rotor of PM brushed DC motors are composed of rotor cores, rotor winding, commutators, and rotating shafts, just like the rotor of ordinary DC motors. Insert the rotor and brush assembly into the stator to form a permanent magnet DC motor.

Small and medium power PM DC motors are widely used in electric bicycles, electric motorcycles, and scooters etc.

Permanent Magnet Synchronous Motor

In recent years, the PM synchronous motor has developed rapidly. Its characteristics are high power factor and high efficiency. In many occasions, it has gradually replaced the commonly used AC asynchronous motor.

Among them, the asynchronous start PM synchronous motor has superior performance and is a very promising energy-saving motor.

How to use the appropriate magnet for PM motor?

Magnet performance

1. The influence of remanence

For DC motors, under the same winding parameters and test conditions, the higher the remanence, the lower the no-load speed and the lower the no-load current; the greater the maximum torque, the higher the efficiency at the highest efficiency point.

2. The influence of coercivity

In the process of motor operation, there is always the influence of temperature and reverse demagnetization. From the perspective of motor design, the higher the coercive force, the smaller the thickness direction of the magnet can be. The smaller the coercive force, the larger the thickness direction of the magnet.

3. The influence of squareness

Squareness only affects the straightness of the efficiency curve of the motor performance test. Although the straightness of the motor efficiency curve has not been listed as an important index standard, this is very important for the continuous travel distance of the in-wheel motor under natural road conditions. important.

4. The impact of performance consistency

Inconsistent remanence and coercivity: even some of the ones with particularly high performance are not good. Due to the inconsistency of the magnetic flux of each unidirectional magnetic field section, the torque is asymmetry and vibration occurs.

Shape and tolerance of magnet

1. Magnet thickness' influence

When the inner or outer magnetic circuit ring is fixed, and when the thickness increases, the air gap decreases and the effective magnetic flux increases.

The obvious performance is that the no-load speed decreases under the same remanence, the no-load current decreases, and the maximum efficiency of the motor improve.

2. Magnet width's influence

In order to ensure the accurate installation position of the motor magnet, we have strict magnet installation procedures to ensure the installation accuracy.

If the width of the magnet is exceeded, it will not be able to be installed; if the width of the magnet is too small, it will cause the magnet to be misaligned, increase the vibration of the motor and reduce the efficiency.

3. Magnet chamfer and non-chamfer's influence

If the angle is not chamfered, the rate of change of the magnetic field at the edge of the magnetic field of the motor is large, causing the motor to pulse. The larger chamfer, the smaller the vibration.

However, chamfer generally has a certain loss of magnetic flux. For some specifications, the magnetic flux loss is 0.5~1.5% when the chamfer is 0.8.

Halbach linear array:

It combines the radial and parallel arrangement of magnets to form a one-sided magnetic field (one-sided field), which is a significant feature of Halbach. This characteristic indicates that Halbach magnets have very good application value in linear motors (linear motors).

Halbach circular array:

It is generally used in brushless AC motors and magnetic couplings to enhance the unidirectional magnetic force, can obtain a nearly perfect sinusoidal magnetic force release. Because it is a unidirectional magnetic force release, non-ferromagnetic materials can be used as the central axis (such as aluminum), which can greatly reduce the overall weight and improve efficiency.

How do we assemble the Halbach array?

It should be noted that the assembly of the Halbach array is extremely difficult, specifically the following points:

-Magnets need to be assembled in a magnetized state, so we must know how to grasp the mutually repelling forces between magnets.

-The magnets in the Halbach array are easier to demagnetize.

-How to design and produce assembly fixtures? It requires a good understanding of the magnetic circuit, and years of experience in assembly of magnetic components.

-Newland Magnetic has many years of industry experience in designing and assembling various magnetic component products by itself. If you have similar problems, please contact us to discuss them.
