Supported motors

Arduino SimpleFOClibrary supports two types of BLDC motors:

• BLDC motors
  • 3 phase (3 wire):
  • Gimbal and High-performance BLDC motors
• Stepper motors
  • 2 phase (4 wire)

📢 Critical: Read before powering up!

Before running any motor, you must ensure your hardware can handle the stall current. FOC can easily pull more current than a driver can handle if not limited in software.

The Worst-Case Calculation Check your motor’s phase resistance (\(R\)) and your power supply voltage (\(V_{DC}\)). The maximum possible current (\(I_{max}\)) is:

\[I_{max} = \frac{V_{DC}}{R}\]

Safety Steps:

• Compare: If \(I_{max}\) exceeds your driver’s rating, you must limit the voltage in software.
• Software Limit: Use driver.voltage_limit and (motor.voltage_limit and/or motor.current_limit) to stay within safe bounds. - see motor docs
• Power Supply: If you can, use a current-limited lab bench power supply for your initial tests.
