Features and Benefits
A typical brushless BLDC motor is constructed using a stator with “slots”; a copper wire is then wound around these slots. Although this technology works well, it has an inherent problem with cogging (or drag torque), which presents a challenge in applications needing fast response, fast acceleration and smooth operation.
To combat these issues, we’ve removed the slots from the motor. Instead of slots, we’re using a unique process of winding the copper wire without the need of them. This drastically reduces cogging and improves the motor’s ability to respond, accelerate quickly, and operate smoothly. Slotless BLDC motors are also quieter and provide more power with a smaller frame size than their slotted counterparts.
Reliable long life expectancy
Our motors are built to withstand at least 20,000 hours of continuous (24/7) operation. This means that you can feel confident that even your most sensitive application will operate reliably for a very long time.
Nearly silent operation
Detent torque is the biggest culprit of generated noise. Removing the slots and thus eliminating the detent torque drastically reduces the noise output of the motor.
Modular design for better customization
The modular design lets us combine the motor with a gearhead to match your specific speed and torque requirements. Also, our slotless BLDC motors are available in many windings so we can satisfy your requirements precisely. You can also customize the motor with sensors such as an optical encoder or hall sensor to provide accurate positioning control, velocity, and direction feedback.
Our unique manufacturing process lets us create motors that are built to your exact specifications, while remaining highly cost effective. Get exactly what you need without breaking your budget.
