Outer rotor motor-W4920A
Outer rotor brushless motor is a type of axial flow, permanent magnet synchronous, brushless commutation motor. It is mainly composed of an outer rotor, an inner stator, a permanent magnet, an electronic commutator and other parts, because the outer rotor mass is small, the moment of inertia is small, the speed is high, the response speed is fast, so the power density is more than 25% higher than the inner rotor motor.
Outer rotor motors are used in a wide range of applications, including but not limited to: electric vehicles, drones, home appliances, industrial machinery, and aerospace. Its high power density and high efficiency make external rotor motors the first choice in many fields, providing powerful power output and reducing energy consumption.
PRODUCT DETAILS
Production introduction
The outer rotor motor reduces the output speed of the rotor group by building the deceleration group into the motor, while optimizing the internal space, so that it can be applied to the field with high requirements for size and structure. The mass distribution of the outer rotor is uniform, and its structural design makes its rotation more stable, and it can maintain relatively stable even under high-speed rotation, and it is not easy to stall. The outer rotor motor because of the simple structure, compact design, easy to replace parts and maintenance operation which result in having a longer life, better applied to the occasion of a longer period of operation. The outer rotor brushless motor can realize the reversal of the electromagnetic field by controlling the electronic components, which can better control the running speed of the motor. Finally, compared with other motor types, the price of the outer rotor motor is relatively moderate, and the cost control is better, which can reduce the production cost of the motor to a certain extent.

FAQ
1. What are your prices?
Our prices are subject to specification depending on technical requirements. We will make offer we clearly understand your working condition and technical requirements.
2.Do you have a minimum order quantity?
Yes, we require all international orders to have an ongoing minimum order quantity. Normally 1000PCS, however we also accept the custom made order with smaller quantity with higher expense.
3.Can you supply the relevant documentation?
Yes, we can provide most documentation including Certificates of Analysis / Conformance; Insurance; Origin, and other export documents where required.
4.What is the average lead time?
For samples, the lead time is about 14 days. For mass production, the lead time is 30~45 days after receiving the deposit payment. The lead times become effective when (1) we have received your deposit, and (2) we have your final approval for your products. If our lead times do not work with your deadline, please go over your requirements with your sale. In all cases we will try to accommodate your needs. In most cases we are able to do so.
5.What kinds of payment methods do you accept?
You can make the payment to our bank account, Western Union or PayPal: 30% deposit in advance, 70% balance before shipment.
