Frameless Torque Motor
- Dynamic Response High Torque Density External Rotor Frameless Torque MotorThe external rotor frameless torque motor is a specialized type of permanent magnet synchronous motor (PMSM) composed of two core components: the rotor and stator. Unlike traditional internal rotor designs, this motor features an externally mounted rotor and an internally positioned stator. The innovative design eliminates traditional motor housings, bearings, and shafts, retaining only the rotor and stator assemblies. The rotor, located outside the stator, integrates permanent magnets with the outer shell and is directly embedded into the load structure. The stator, positioned internally, contains copper windings and laminations, driving the external rotor’s rotation via electromagnetic forces. This design combines the high moment of inertia of the external rotor configuration with the compactness of the frameless structure, making it ideal for applications requiring low-speed high-torque output and efficient heat dissipation, such as medical equipment, industrial fans, and automated industrial systems.Details
Compact Lightweight High Power Density Internal Rotor Frameless Torque MotorThe internal rotor frameless torque motor is a specialized type of permanent magnet synchronous motor (PMSM) composed of two core components: the rotor and stator. The rotor is internally positioned, while the stator is externally mounted. Its innovative design eliminates traditional motor housings, bearings, and shafts, retaining only the rotor and stator assemblies. The rotor typically adopts a ring-shaped structure integrated with permanent magnets, directly mounted on the load shaft. The stator consists of copper windings and laminations, generating electromagnetic forces to drive rotor rotation. This configuration achieves torque output through efficient magnetic field interaction, making it ideal for high-precision applications such as robotic joints and industrial automation. It enables direct load driving, minimizing mechanical transmission losses.Details
Company Introduction
HONPINE is a leading provider of precision transmission solutions, founded in 2018 by Allen who possesses extensive expertise in precision mechanical design, gear transmission systems, transmission system design, tolerance analysis and manufacturing, servo control technology, and robotic joint design. With continuous dedication to advancing knowledge in precision transmission systems and gear machining technologies, Allen established HONPINE with the mission to deliver exceptional transmission solutions. The company operates under the philosophy that "Great things take time - we're building for the long term," reflecting our belief in the power of gradual accumulation. Through persistent research, development, self-reflection and growth, especially during the most challenging periods, we have achieved remarkable progress when the timing was right.
What is the encoder resolution of your joint modules?
Our harmonic drive modules feature a high-precision 16-bit encoder resolution, providing 65,536 discrete positions per revolution. This means the full 360° rotation is divided into extremely fine increments for exceptional positional accuracy at the motor end.
Do your harmonic joint modules include STO (Safe Torque Off) functionality?
HONPINE harmonic drive modules utilize a different safety approach. Instead of STO, we incorporate a reliable built-in electromagnetic brake system that automatically engages to stop rotation immediately when power is disconnected, ensuring safe operation.
Can the harmonic drive modules provide torque measurement?
While HONPINE standard robot joint modules don't include integrated torque measurement, we can accommodate torque sensing requirements by integrating an external torque sensor. Please contact our technical team for customized solutions.
Are general-purpose I/O interfaces available on the harmonic drivemodules?
Due to the highly compact design of our integrated driver system, HONPINE current robot joint modules don't include general-purpose I/O pins. This streamlined design allows for optimal space savings in robotic applications.
Where can I find detailed specifications about mass and dimensions?
Complete mechanical specifications including mass and volume for all module variants are available in our Model Selection Brochure. Download the brochure from our resources section or contact our sales team for specific dimensional requirements.
What type of encoder does the HONPINE joint motor use?
The HONPINE joint motor uses a magnetic encoder with a resolution of 65,536 units per revolution.
Does the HONPINE joint motor use an absolute encoder?
Yes. It employs a multi-turn absolute encoder. However, due to a reduction gear at the output, an encoder battery is required to retain the multi-turn position count. Customization is supported, allowing the option to have the motor with or without the encoder battery.
What is the control frequency of the joint module?
Based on the CAN protocol, a single motor requires 0.5ms for each transmission and reception. For multiple motors, this time accumulates accordingly.
If one main controller manages two joint modules, would using more main controllers suffice to achieve a 1kHz control frequency?
Essentially, one main controller can handle four modules. While the normal communication cycle is 0.5ms per transmission, it does not consistently maintain this interval—for instance, high-frequency sampling is unnecessary during alarm states or similar conditions.
