Integrated High-Precision Magnetic Encoder

This motor includes a factory-integrated AS5600 magnetic encoder that delivers 12-bit position resolution with an angular measurement accuracy of 0.087°. This high-resolution feedback is essential for implementing closed-loop FOC systems, allowing accurate control of:

• Motor position
• Rotation speed
• Torque output

The encoder supports I2C, PWM, and analog outputs, making it highly adaptable for different embedded control systems.

Optimized for Field-Oriented Control (FOC)

The 4015 BLDC motor is specifically designed for FOC (Field-Oriented Control), also known as vector control. Compared to conventional motor control methods, FOC offers:

• Smoother motion
• Reduced torque ripple
• Lower operational noise
• Improved efficiency
• Better low-speed stability

This makes the motor ideal for applications where quiet, precise, and stable motion is required.

High-Torque Hollow Shaft Design

Built with a neodymium iron boron outer rotor and a durable aluminum alloy housing, this motor offers a strong torque-to-size ratio while maintaining compact dimensions.

Its 7.5mm hollow shaft design allows wires or mechanical components to pass through the motor center, making it especially useful for:

• Robotic joints
• Gimbal systems
• Compact automation assemblies
• Cable-managed rotating systems

Broad Compatibility & Open-Source Support

This motor is fully compatible with the SimpleFOC ecosystem, making it ideal for developers, students, and engineers working on advanced motor control projects.

It can be easily integrated with popular development platforms such as:

• Arduino
• Espressif Systems (ESP32)
• Raspberry Pi

This broad support helps accelerate rapid prototyping, learning, and deployment.
