Acionamento Six step block

Acionamento six-step block

Description

Implements the algorithm for six-step commutation (also knows as block-commutation) of the BLDC.

Parameters and ports

Parameters

• Número de pólos do motor: Number of poles of the motor.

Inputs

• V: Voltage to be applied at each phase when it is commutated, e.g. for a 12V motor, this should be 12,0 for full-speed rotation.
• theta_m: Angular position of the rotor. [radians]

Outputs

• Va: Voltage to be applied to the motor's phase 'a'. [V]
• Vb: Voltage to be applied to the motor's phase 'b'. [V]
• Vc: Voltage to be applied to the motor's phase 'c'. [V]
• Halls: 3x1 vector with the logical values of each hall sensor.
  • hall1: active between 300 and 120 degrees
  • hall2: active between 60 and 240 degrees
  • hall3: active between 180 and 360 degrees
