Frequently Asked Questions

What motor types are supported by this solution?

This industrial motor control solution supports three-phase brushless DC (BLDC) motors and permanent magnet synchronous motors (PMSM). The FOC algorithm is optimized for PMSM motors but also works well with BLDC motors using sinusoidal commutation. Motor voltage ratings from 12V to 36V are supported, with power levels up to 1kW continuous. The sensorless control works best with surface-mount magnet motors

interior magnet motors may require Hall sensors for reliable operation. For specific motor compatibility, provide motor datasheet to LiTong FAE team for evaluation.

Solution is ideal for PMSM and BLDC motors from 200W to 1kW. Contact our FAE team for motor compatibility verification.

What is the minimum speed for sensorless operation?

The sensorless FOC implementation typically supports operation down to 10% of rated motor speed without Hall sensors. Below this speed, back-EMF signal becomes too weak for reliable position estimation. For applications requiring lower speeds, several options are available: 1) Use Hall sensors for position feedback at all speeds. 2) Implement high-frequency injection for zero/low-speed operation. 3) Use open-loop control with current limit for startup and very low speeds. For most pump and fan applications, 10% minimum speed is adequate. For servo applications requiring full torque at zero speed, Hall sensors are recommended.

Sensorless operation down to 10% speed. Add Hall sensors for applications requiring lower speeds or full torque at standstill.

How do I tune the FOC parameters for my motor?

FOC parameter tuning involves several steps: 1) Motor Parameters - Measure phase resistance (R) and inductance (L) using LCR meter. These values are critical for current loop PI controller tuning. 2) Current Loops - Tune d-axis and q-axis current PI controllers using standard methods (Ziegler-Nichols or manual tuning). Target bandwidth of 1-2kHz for good dynamic response. 3) Speed Loop - Tune speed PI controller with lower bandwidth (100-500Hz) than current loops. 4) Observer Gains - Adjust sliding mode observer gains for optimal position estimation. XHSC provides an auto-tuning tool that can help with initial parameter estimation. Contact LiTong FAE for detailed tuning guidance.

Start with XHSC auto-tuning tool, then fine-tune manually for optimal performance. Contact our FAE team for tuning assistance.

What communication protocols are supported?

The industrial motor control solution supports multiple communication interfaces: 1) RS-485 - Half-duplex RS-485 with Modbus RTU protocol for industrial network integration. Supports up to 115.2kbps. 2) CAN - CAN 2.0B interface with CANopen or custom protocols for automotive and industrial applications. 3) Analog - 0-10V or 4-20mA analog input for speed reference. 4) Digital I/O - Start/stop, direction, and fault signals. 5) PWM Input - Speed reference via PWM duty cycle. The firmware can be customized to support additional protocols as needed. Contact LiTong for protocol implementation support.

RS-485 with Modbus is standard. CAN interface available for automotive applications. Contact us for custom protocol implementation.
