Description of Brushless motors

●What is a brushless motor?

Brushless motors are designed without the brushes and commutators found in brush motors (such as coreless motors), instead incorporating an electrical control mechanism. To operate, they require a control circuit, which uses Hall ICs to detect the magnetic force of the rotor and electrically control its rotation. Additionally, the absence of brush and commutator friction results in a longer motor lifespan compared to brush motors.

●Features of brushless motors

･Long life
Since there are no brushes, there is no wear on the brushes or commutator, so the motor's service life is determined by the bearing life.
Therefore, selecting appropriate bearings can enable long-lasting motor usage.

･Smooth rotation (cogging-free) and high-speed rotation
Our brushless motors have a slotless structure, enabling smooth rotation.
Additionally, the absence of mechanical losses caused by brushes and commutators enables higher rotational speeds compared to core-less motors.

･Low Vibration and low noise
The absence of mechanical contact between brushes and commutators allows for reduced vibration and noise compared to brush motors.

●Why choose our brushless motors?

･Output Shape
Our strength lies in our ability to customize according to customer requirements, so we can consider the shape of the output shaft based on your needs. Please feel free to consult with us. The basic interface of our brushless motors includes terminals for supplying voltage to the windings U, V, and W, three outputs from the Hall ICs, and eight terminals including power supply and GND for the Hall ICs.

･Low Vibration and low noise
Some of our customers have praised our motors for their low vibration and quiet operation. Our motors excel in applications where rotational noise is a concern, such as servo systems and fan-equipped masks. We have implemented measures to suppress imbalance caused by variations in magnets.

･Excellent controllability
There are structures with slots to house the coils in the motors, and those without slots. While slots can prevent the motor from overheating, they also risk affecting motor performance and causing cogging. Our motors adopt a slotless structure, eliminating cogging and providing excellent controllability.

FAQ

Q1 difference in life expectancy between coreless motors and brushless motors.
Answer

Brushless motors tend to have a longer service life, partly because brushless motors have no brushes.

Q2 how long is the life of the motor?
Answer

Depending on the conditions of use, they generally have a life span of several hundred to several thousand hours.

Q3 What is the maximum rotational speed?
Answer

For coreless motors, the guideline is 20,000 r/min, and for brushless motors, it is 40,000 r/min.

Q4 for which application is it suitable?
Answer

Suitable for precision equipment and applications requiring low power consumption, such as surgical support robots, drones, semiconductor manufacturing equipment, analyzers, electronic locks, and pumps.

Q5 what is the efficiency of the motor?
Answer

They generally boast high efficiency of over 80%, but it varies by model.

Q6 is it waterproof and dustproof?
Answer

At this time, there is no corresponding track record.

Q7 what is the size and weight of the motor?
Answer

The lineup ranges from 4 to 22 mm in diameter. Weight varies depending on the model, but ranges from 0.5 to 80g.

Q8 can you provide samples?
Answer

Samples can be provided. Please contact us for details.

Q9 what is your turnaround time?
Answer

Delivery is expected to take 3 months due to the time required to order parts for customization, but delivery can be made within 1 month depending on the parts inventory and manufacturing schedule.

Q10 what is the operating temperature range of the motor?
Answer

The proven track record is to operate in ambient temperatures ranging from -40°C to +60°C, but it depends on the model.

Q11 Please tell us about the motor control methods.
Answer

They are used in various control methods such as PWM control and voltage control.

Q12 what is the noise level of the motor?
Answer

The standard is less than 40 dB, resulting in low noise.

Q13 Please tell me about the motor mounting method.
Answer

It can be mounted using the outside diameter of the motor or secured using the motor mounting surface.

Q14 how can i get technical support?
Answer

Support can be provided by phone or email. We may also be able to provide on-site support, depending on the nature of your consultation.

Q15 What is C.I. TAKIRON's MOQ (minimum order quantity)?
Answer

Prices vary greatly depending on the quantity ordered, but for some products, orders can be placed for as little as 100 pieces.

Q16 do you have any catalog items (stock)?
Answer

All are made to order, but we may be able to provide them. Please contact us.

Q17 where is your production site?
Answer

Our production sites are located in Japan and China.

Q18 can i submit environmental data?
Answer

European chemical regulations such as REACH and RoHS directives for motor products are complied with upon customer request.

Q19 Is the factory ISO certified?
Answer

Our main manufacturing base, Shanghai Kiai Chemical & Electronics Co., Ltd. has acquired ISO 9001 and ISO 14001 certification. No other manufacturing bases have obtained these certifications.
