Description

Λ7 3GTG61 V. Description of the invention (/) The present invention is a motor whose rotor and stator are of multi-pole structure 'and each pole is separately moved with a small power crystal. Significantly improve the use of high-power crystals with high unit prices in the past; or avoid the complicated technology of paralleling small power crystals into high-power to drive motors and additional external protection circuits, which can reduce driving costs and increase reliability. Traditional pole drive motors must be paralleled with small power crystals to form high powers to drive the motors / or use high-power crystals with high unit prices to drive the motors. But Fu Tong ’s parallel drive must have an external protection circuit. When U is damaged by any power crystal, the abnormal temperature rise due to the increase in current of other power crystals and the thermal balance problem caused by it .. So there is a cost. The shortcomings of reliable, low friction, etc. Han. On the other hand, if you do not use parallel low-power crystals and use high-power crystals, not only the unit price of power crystals, the drive control circuit is complicated, but also an external protection circuit is required; therefore, it also has the above-mentioned disadvantages. Therefore, it can be seen from the foregoing that when using a power crystal to drive a pole drive motor, if you want to reduce costs and improve reliability, you should at least have (1) low-cost circuits: no additional external protection circuits are required, and no large unit price is required. Power crystal and complex drive control loop, and disperse the power to each independent low-power crystal with low unit price. (2) Supply power in a fault-tolerant (FauU-Tmlance) manner: Instead of using high-power crystals, the required power is divided. Separate small independent power crystals, the damage of a small power crystal will not cause the entire. Reading circuit Overheating and damage, while still keeping the motor running, greatly improving its reliability. Compared with the above two types of Futong drive motors, the effect of cost reduction and reliability improvement is very obvious. Secondly, the purpose of this invention is to provide a low-cost and highly reliable motor, so that each magnetic pole is driven by an independent low-unit price low-power crystal to provide its required electrical energy, without using a high-unit price high-power crystal . Simplify the drive control circuit and eliminate the external protection circuit, greatly improve its reliability and reduce costs.

I * · · · Each pole is driven by a low-power low-power crystal separately, instead of using a high-power crystal with a high unit price, or paralleling a small-power crystal into a high-power to drive the motor. 'So no-complex drive control loops and external protection loops are required. In addition, it is also easy to disperse. : The present invention can be understood by the following diagrams and descriptions. The first figure is a schematic diagram of the principle of the two-bar power supply system of a traditional pole drive motor. The second picture of ‘i I is a schematic diagram of the principle of a low-power sub-magnetic drive_motor. 'I' ': As shown in < First Picture >, there are two ways to supply power to a conventional pole drive motor. Gan Yi is a high-power crystal with high unit price, as shown in (a) '. If the motor (1) is 1.5kW, the power crystal ⑵ is also HW, which is enough to drive the motor. At this time, the power of 1.5kW must be evenly distributed to all magnetic poles. Therefore, not only the unit price of the power crystal is high, but also a complex drive control circuit and an external protection circuit are required, so the cost is high and the reliability is low. Another way is to connect the power of the small work f crystal (2) in parallel to a large power to supply the motor (1). As shown in (b), if the motor (1) is 1.5kW, several small power crystals (2) are connected in parallel so that the power reaches 1.5kW. At this time, the power of UkW must be equally distributed to all magnetic poles. In order to avoid the damage of any power crystal, the abnormal temperature rise due to the increase of the current of other power crystals, and the thermal balance problems caused by it, there must also be an external protection circuit, so it also has the disadvantages of high cost and low reliability. As shown in < Second Picture >, the present invention distributes the required power to each independent low-power crystal (2), and each magnetic pole (Π) of the motor (1) uses a low-power low-power crystal (2) Drive separately, without using large-rate crystals with high unit price, or paralleling small-power crystals into high-power to drive the motor. When the power crystal is damaged, it will not cause the failure of the function of the entire power supply system. At most, it will only be able to run smoothly, and it can still maintain the operation of Ma Mo. In addition, it is easy to dissipate heat. Therefore, there is no need for an external protection circuit, and the large-scale paper hate the standard / Π 中 罔 Minjia family dispute (CNS) Λ4 ni pile (2 丨 〇297 297).
