Tangential magnets polarization
The tangential polarization of our magnets significantly enhances the magnetic field concentration, surpassing the efficiency of an array of Halbach magnets. Here are some key benefits and features:
- Enhanced Magnetic Field: By utilizing tangentially polarized magnets, we can concentrate the magnetic field more effectively, leading to improved motor performance.
- No Glue Required: Our design does not require glue to install the magnets. This not only simplifies the assembly process but also allows for easy removal and re-magnetization if necessary.
- Higher Torque Density: The straightforward construction of our inrunner motors, combined with tangential magnet polarization, allows us to achieve a higher torque density compared to outrunner motors of the same diameter and weight. This means our motors can deliver more torque without increasing size or weight.
Grain Oriented (GO) Steel
Using Grain Oriented (GO) steel in the stator teeth and core of our motors brings several performance benefits:
- Improved Performance: GO steel enhances the motor’s performance by approximately 5% compared to non-oriented steel. This is due to its superior magnetic properties.
- Higher Saturation Value: The higher saturation value of GO steel allows us to design stator teeth with a smaller width. This means the stator can handle higher levels of magnetic flux without becoming saturated.
Rectangular copper wire
Using rectangular copper wire in our motor coils offers significant advantages:
- Higher Fill Factor: Rectangular copper wire increases the fill factor to about 70%, meaning there is more copper wire packed into the same space compared to round wire. This maximization of space improves the efficiency of the motor.
- Increased Current Density: The higher fill factor leads to increased current density in the motor coils. This allows the motor to handle more current, resulting in improved performance and efficiency.
IP65 Design
Our motors feature an IP65 fully sealed construction, providing several key benefits:
- Fully Sealed Construction: The IP65 rating means that our motors are fully protected against dust ingress and low-pressure water jets from any direction. This robust sealing ensures reliable operation in challenging environments.
- Difficult Environment Conditions: Thanks to the IP65 design, our motors can perform effectively in difficult and harsh conditions, including exposure to dust, dirt, and moisture, without compromising performance or durability.
High-Efficiency Cooling Structure
Our motors feature a high-efficiency cooling structure designed to maximize heat dissipation from the coils:
- Open Stator Construction: The open stator design, with teeth positioned between the coils, provides ample surface area for heat dissipation, enhancing the motor’s cooling efficiency.
- High Thermal Conductivity Insulating Paper: We use high thermal conductivity insulating paper in our motors, which helps transfer heat away from the coils more effectively.
- Impregnation Varnish: The coils are coated with a special impregnation varnish, which further aids in efficient heat removal by enhancing thermal conductivity and protecting the coils from environmental factors.
