Brushless motor systems require position and current sensors for control. At least two-phase currents are necessary for controlling a three-phase brushless motor. Current sensing can be achieved by detecting the phase currents from the direct current bus, making one sensor sufficient for current control in brushless motors

Placing the Hall sensors of a brushless DC motor opposite the magnetic wheel formed by the shaft or rotor extension can detect the rotor’s position. However, this only provides enough commutation signals

Up until now, the majority of people lack awareness of brushless DC motors and drivers, even though they may have encountered them in everyday appliances like air conditioners, washing machines, electric fans, hairdryers, etc.

Stepper motors can be classified into three main types based on their structural forms: Variable Reluctance (VR), Permanent Magnet (PM), and Hybrid Stepping (HS) motors. The operational performance of stepper motors is closely related to their control methods, which can be categorized into three types:

When a stepper motor becomes stuck, it indicates insufficient torque even when the motor and its driver are undamaged. When the stepper motor is fixed in place, the primary factors affecting torque are speed and current

When selecting a stepper motor, it’s crucial to consider the advantages and disadvantages of various motor types. Let’s explore the pros and cons of stepper motors with different phase numbers:

Planetary gear reducers are widely used in the transmission systems of control motors such as servo motors, stepper motors, and brushless DC motors due to their high precision, small size, high transmission efficiency, and wide range of reduction capabilities.

During the operation of a planetary gearbox, its iron core is subjected to alternating magnetic fields, resulting in iron losses. Additionally, the motor winding, when energized, generates copper losses along with other associated losses.

Electric motors are essential devices that convert electrical energy into mechanical motion. But how exactly do electric motors work to spin motors and generate torque?

Brushless DC (BLDC) motor bearings, also known as electric motor bearings or motor bearings, are specialized bearings designed specifically for use in electric motors and drives. Bearings support and guide the motor shaft while allowing it to rotate smoothly
