This article provides a comprehensive introduction to brushless motor bearings, focusing on the reasons behind overheating and effective solutions.

I. Understanding Bearing Overheating

In general terms, bearing overheating refers to a temperature exceeding 95°C for rolling bearings and 80°C for sliding bearings.

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

The two-phase four-wire stepper motor, as a digital actuator, has found widespread applications in motion control systems. Many users may experience significant heating when using the two-phase four-wire stepper motor

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.

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 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.

High-power brushless DC motors find various applications in the automotive industry, primarily in wheel drive, air conditioning compressors, air conditioning blower fans, purifiers, exhaust fans, and more. Let’s explore these applications further with insights from Faradyi Motors: These are the applications of high-power brushless DC motors in the automotive industry.

DC servo motor controllers involve various gain adjustments to optimize performance. Faradyi Motors will break down these adjustments

In the realm of industrial automation, the closed-loop control system for low-voltage DC servo motors is a pivotal technology. In layman’s terms, “closed-loop” signifies a continuous cycle where the motor receives instructions and provides corresponding responses. This interaction is characterized by digital commands and data-driven responses.

DC servo motor encoders are rotational sensors that convert rotary displacement into a series of digital pulse signals. These pulses play a crucial role in controlling angular displacement, and when coupled with gear racks or screw threads, they can also be utilized for linear displacement measurements.
