Q2: What is the rated operating voltage for the Coreless DC Motor series?
The coreless DC motor operates at a nominal voltage of 24.0V DC, delivering high power density, exceptional maximum efficiency (up to 81.7%), and ultra-smooth rotation across its full speed range.
Q3: Can these motors be customized according to specific OEM requirements?
Yes, we offer custom shaft lengths, custom mounting flanges, tailored wiring harnesses, drive controller integration, and custom IP protection ratings based on your OEM project specifications.
Q4: What is the typical noise level during operation?
The typical operating noise level is strictly maintained at ≤ 45 dB, making these motors ideal for noise-sensitive medical therapy, sleep devices, and indoor laboratory instruments.
Q5: What are the stall torque and maximum output power ratings?
Under 24.0V nominal operation, the coreless DC motor delivers a stall torque of 117.9 mNm and achieves a peak power output of 38.3 W at 6,200 rpm.
Q6: What protection level (IP rating) does the motor feature?
The standard unit is rated at IP54 protection level, providing resistance against dust ingress and water splashes to ensure high reliability in industrial and medical environments.
Q7: Why choose a coreless motor design over conventional BLDC motors?
Coreless motor designs eliminate iron losses, significantly reduce rotor inertia (6.40 gcm²), eliminate cogging torque, and offer rapid acceleration with extremely low vibration.
Q8: How is speed and torque controlled in these high-speed motors?
Speed and torque can be precisely controlled via external PWM or analog voltage signal drivers, utilizing hall sensors or sensorless feedback mechanisms depending on the system controller design.
Q9: What is the mechanical time constant for these coreless motors?
The mechanical time constant is as low as 2.65 ms, enabling rapid acceleration and instant adjustment to dynamic pressure fluctuations in medical ventilation.
Q10: What bearing types are used to ensure long service life?
High-precision, pre-lubricated stainless steel ball bearings are utilized to handle high rotational speeds (up to 12,400 rpm no-load speed) and maintain long-term operational durability.
