Motor Drive
GaN Reduces Size and Weight, Reduces Audible Noise, Enables Precision Control

Brushless DC (BLDC) motors find extensive use in industrial sectors, including robotics, e-mobility, and unmanned aerial vehicles (drones). Leveraging the compact design, thermal efficiency, and high-frequency switching capabilities of GaN FETs and ICs, these motor drives achieve unparalleled compactness, precision, and reduced noise levels.

Key Advantages of GaN-Based Motor Drives:

  • Optimized Efficiency: Minimal dead times contribute to exceptional motor and inverter system efficiency, extending operational range.
  • Acoustic Noise Reduction: GaN's lower distortion levels result in quieter operation, ideal for noise-sensitive environments.
  • Enhanced Precision: Reduced current and torque ripple contribute to greater motor control accuracy.
  • Compact and Powerful: The lightweight and small footprint of GaN solutions facilitates their integration into the motor housing, supporting motors with low inductance and high power density.

Configured for high-frequency operation, GaN technology allows for a significant reduction in the number of input filter capacitors. This can eliminate the need for electrolytic capacitors on the board, resulting in cost savings, space optimization, and increased reliability.
