Sanyo brushless DC motors are high-performance motors. The following sections will elaborate on their characteristics, application fields, working principles, and other aspects:
I. Working Principle
A brushless DC motor consists of a motor body and a driver, making it a typical mechatronic product. The stator windings of the motor are mostly arranged in a three-phase symmetric star connection, which is very similar to that of a three-phase asynchronous motor. Permanent magnets are mounted on the rotor. When three-phase alternating current is passed through the stator windings, a rotating magnetic field is generated. Under the action of this rotating magnetic field, the rotor rotates in the direction of the rotating magnetic field. By controlling the magnitude and direction of the current in the stator windings through the driver, the speed and direction of the motor can be controlled.
II. Characteristics
1. Performance
（1）High Energy Efficiency: Compared with traditional DC motors, Sanyo brushless DC motors have higher energy conversion efficiency, which can effectively reduce energy consumption. For example, the power loss of Sanyo’s SANMOTION K series brushless DC motors is reduced by approximately 30% and their efficiency is increased by 10% compared with traditional models.
（2）High Speed and High Torque: They can output large torque at high speeds, meeting the power requirements of different application scenarios. For instance, some models can reach a maximum speed of tens of thousands of revolutions per minute while maintaining stable torque output.

（2）Wide Speed Regulation Range: Smooth speed regulation can be performed within a wide speed range, meeting the diverse speed requirements of different application scenarios, and the speed regulation ratio can reach a high value.
4. Other Advantages
（1）Maintenance-Free: Since there are no easily wearable components such as brushes and commutators, Sanyo brushless DC motors do not require regular brush replacement, greatly reducing maintenance workload and costs.
（2）Compact Size and Light Weight: Under the same power output, Sanyo brushless DC motors are smaller in size and lighter in weight than traditional DC motors, facilitating installation and use, and effectively saving equipment space.
III. Application Fields

They can precisely control the movement of mechanical components, improving production efficiency and product quality.
（2）Electronic Equipment Manufacturing: Used in semiconductor manufacturing equipment, LCD panel production equipment, etc., to achieve high-precision positioning and motion control, ensuring the accuracy and stability of the equipment.
（3）Medical Devices: Equipment such as medical robots, precision surgical instruments, and medical testing devices require high-precision motion control to ensure the accuracy and safety of medical operations.
（4）Aerospace: Applied in various aerospace equipment, such as the attitude control of aircraft and the control systems of aero-engines. These applications require motors to have high reliability, high precision, and lightweight characteristics.
（5）Smart Home: Commonly used in smart home devices, such as air conditioners, refrigerators, washing machines, and vacuum cleaners, providing efficient, energy-saving, and quiet power support for these devices.
IV. Key Selection Criteria
（1）Power: Select a motor with appropriate power based on the power required in the actual application scenario to ensure that the motor can meet the load requirements while avoiding resource waste due to excessive power.
（2）Speed: Choose a motor with a suitable speed range according to the operating speed requirements of the equipment to ensure that the motor speed can meet the working needs of the equipment.
（3）Torque: Consider the torque required by the load and select a motor that can provide sufficient torque to ensure that the motor can drive the load to operate normally and avoid overload.
（4）Control Method: According to the control requirements of the equipment, select a motor with the corresponding control method, such as analog control, digital control, or bus control, to achieve precise control of the motor.
V. Application Cases of Sanyo Brushless DC Motors in Industrial Robots and Other Fields
Compared with other motors, Sanyo brushless DC motors have advantages such as high efficiency, precise control, strong reliability, and low electromagnetic interference in the field of industrial robots.
（1）SCARA Robot Application Case: Sanyo provides automation products for SCARA robots, including its AZ series motors, actuators, and network drivers, which are equipped with absolute sensors and closed-loop control functions and can be used with multi-axis MRC0L controllers. A certain type of horizontal SCARA robot adopts AZ series DC input motors, combined with DGII series hollow rotating actuators and DR series compact linear actuators. It integrates the transportation and additional positioning actions between adjacent process equipment, addressing the issue of limited equipment width and height, and reducing the difficulty of automated design.
（2）Welding Robot Application Case: In welding robots, the jog function of Sanyo brushless DC motors enables micro-movement of the robot, allowing precise control of welding position and speed, and improving welding quality and efficiency. For example, in the welding process of an automobile production line, robot joints need to move frequently and accurately. The high-precision control capability of Sanyo brushless DC motors ensures that the robot can achieve repeated positioning with extremely high precision, with errors controlled within a very small range, thus ensuring the accuracy of the welding position.
（3）Joint Drive Application Case: A well-known industrial robot manufacturer applies Sanyo brushless DC motor drivers to the joint drive units of the industrial robots it produces. The brushless DC motor drivers provide powerful and precise power output for the joints of industrial robots, and can quickly and accurately adjust the motor speed and direction according to control commands, enabling smooth and flexible movement of the robot joints. The working efficiency of industrial robots equipped with this motor driver is 40% higher than that of robots with traditional drive methods, and the operation accuracy is improved to ±0.1 mm.
