Reasons and Solutions for Brushless Motors Failing to Start
Low Power Supply Voltage or Excessive Voltage Drop during Startup:
If the power supply voltage is too low, investigate the root cause.
If excessive voltage drop occurs during startup, consider raising the startup voltage. For systems using autotransformer starting devices, adjusting the tap position can increase the startup voltage.

Maintenance Tips for Hybrid Stepper Motors
The hybrid stepper motor is designed by integrating the advantages of permanent magnet and variable reluctance stepper motors. It is further divided into two-phase, three-phase, and five-phase hybrid stepper motors, with a typical step angle of 1.8° for two-phase, 1.2° for three-phase, and 0.72° for five-phase.
Analysis of Pole Pairs in Brushless Motors
The pole pairs of a brushless motor are determined by detecting changes in the magnetic field of the rotor. The rotor magnetic steel is arranged alternately as N-pole and S-pole. When the Hall sensors of the brushless motor detect a transition from N-pole to S-pole or from S-pole to N-pole, the Hall’s output undergoes corresponding high and low level changes, indicating a change in the rotor’s position
Analysis of Silicon Steel Sheets in Brushless Motors
The rotor of a brushless motor consists of two parts: an internally composed rotor core made of silicon steel sheets and a surface-mounted permanent magnet. This is the surface-mounted permanent magnet structure.
