Industrial Motor Control Solution

The Novosense motor control solution supports various motor types through appropriate control algorithm implementation: AC Induction Motors (ACIM) using V/Hz control or field-oriented control (FOC) with the isolated gate drivers providing robust switching. Permanent Magnet Synchronous Motors (PMSM) including surface-mounted and interior permanent magnet types using FOC with current feedback from NSC2860 sense amplifiers. Brushless DC Motors (BLDC) using trapezoidal commutation with Hall sensor or sensorless control. The solution provides the isolation and sensing infrastructure

the specific motor control algorithm is implemented in the MCU. For servo applications requiring precise position control, the isolated communication interface enables connection to encoders and industrial networks.

This solution provides isolation and sensing for any motor type. Select your MCU and implement appropriate control algorithm (V/Hz, FOC, or BLDC). Contact BeiLuo for specific motor control recommendations.

Overcurrent protection is implemented using the NSC2860 current sense amplifiers and external comparators: The NSC2860 monitors motor phase currents with 3% accuracy and 400kHz bandwidth. Output is fed to fast comparators (response time <1us) with adjustable thresholds. When overcurrent is detected, the comparator output triggers immediate shutdown through the gate driver disable pins. Hardware protection operates independently of software for fastest response. Software monitoring provides additional protection with programmable thresholds and fault logging. For short-circuit protection, desaturation detection can be added to the gate drivers for IGBT protection. I recommend implementing both hardware fast protection (<5us response) and software protection (<100us response) for comprehensive fault coverage. The reference design includes example protection circuits and recommended component values.

Implement hardware overcurrent protection using NSC2860 and fast comparators for <5us response. Add software monitoring for programmable thresholds and diagnostics. Follow reference design protection circuit examples.

EMC design is critical for reliable motor control operation: The Novosense gate drivers provide high CMTI (>150kV/us) to prevent false triggering from switching transients. Isolation barriers naturally attenuate common-mode noise between control and power stages. For conducted emissions, proper input filtering on the DC bus is essential. For radiated emissions, shielded cables for motor connections and proper PCB layout with ground planes are recommended. The reference design includes EMC-optimized PCB layout with proper creepage distances, ground plane segmentation, and filtering. For severe industrial environments, additional external filtering may be needed on power and communication lines. All Novosense products are tested to industrial EMC standards including IEC 61800-3 for motor drives.

Follow reference design PCB layout for EMC optimization. Add external filters for severe environments. Test EMC performance early in development. Contact BeiLuo FAE for EMC design review.
