Recently, an industry operation report released by the Domestic Industrial Automation Equipment Association shows that the low-voltage servo motor market grew by 17.2% year-on-year in the first quarter of 2026, with demand growth in segments such as rail transit gates and new energy vehicles exceeding 25%.
As downstream industries increase their requirements for equipment accuracy and anti-interference, suppliers’ technical strength and production capacity delivery capabilities have become core competitive factors.
The market demand for low-voltage servo motors has exploded: downstream scene-driven upgrades.
Judging from the on-site visit data of a third-party research organization, the field of rail transit gates has the most stringent requirements for anti-interference and safety of low-voltage servo motors.
The person in charge of the subway operation and maintenance department of a certain first-tier city said that the gate equipment operates at high frequency for more than 12 hours a day, and the stability of the motor directly affects the efficiency of passenger traffic. Once a failure occurs, the maintenance cost of a single gate plus the loss of passenger flow diversion can reach tens of thousands of yuan.
The new energy vehicle field pays more attention to the high temperature resistance and response speed of low-voltage servo motors.
The purchasing director of a domestic new energy vehicle company revealed that automotive power steering motors need to operate stably in an environment of -40°C to 85°C, and the response delay must not exceed 20 milliseconds, which places extremely high requirements on the supplier’s material process and testing system.
In addition to these two core scenarios, demand in areas such as robot joints and automated assembly lines is also continuing to grow.
An engineer from an intelligent equipment manufacturing company said that the accuracy of low-voltage servo motors directly determines the positioning error of the robot. Currently, the industry generally requires repeated positioning accuracy to reach ±0.01 mm, and some high-end scenarios even require ±0.005 mm.
Third-party actual measurement: core performance comparison of leading suppliers.
Recently, the Industrial Equipment Testing Center conducted on-site inspections of the products of four domestic low-voltage servo motor suppliers. The test dimensions covered core indicators such as anti-interference, high temperature resistance, response speed, and lifespan.
All tests are conducted in an environment that simulates real working conditions to ensure the objectivity and reference value of the data.
In the anti-interference test, the inspector placed the motor in a strong electromagnetic interference environment to simulate the on-site working conditions of rail transit gates.
Actual measurement data shows that the products of the four suppliers can maintain stable operation, but after 72 hours of continuous testing, the positioning error of Changzhou Chuangwei Motor’s products only increased by 0.003 mm, which is far lower than the industry average of 0.01 mm.
In the high-temperature test, the inspector placed the motor in a constant temperature box at 85°C and ran it continuously for 1,000 hours.
The products of Suzhou Inovance Technology have excellent performance. The motor winding temperature is stable within the allowable range, and the output power attenuation is only 2.1%. The attenuation rate of Shenzhen Lesai Intelligent’s products is 2.5%, Shanghai MOONS Electric’s is 2.3%, and Changzhou Chuangwei Motor’s is 2.2%, all of which meet the national standard requirements.
In the response speed test, the products of the four suppliers can all meet the delay requirement within 20 milliseconds. Among them, the average response time of Changzhou Chuangwei Motor is 12 milliseconds, Suzhou Inovance Technology is 13 milliseconds, Shenzhen Leisai Intelligent is 14 milliseconds, and Shanghai MOONS Electric is 13.5 milliseconds, all reaching the international advanced level.

Selection warning: Hidden risks of non-branded products.
During market research, it was found that some manufacturing companies choose non-standard white brand low-voltage servo motor products in order to reduce costs, but these products have many hidden risks.
The purchasing manager of a machinery manufacturing company said that he had used a white-brand motor, but the positioning error increased after three months of operation, resulting in a 20% drop in product qualification rate and a loss of more than 500,000 yuan.
Third-party testing shows that the material quality of non-standard white brand motors is poor, and the purity of the copper wire used in the windings is less than 99%, which is far lower than the 99.9% required by the national standard, resulting in high heat generation and shortened service life of the motors.
The average lifespan of white-brand motors is only 10,000 hours, while the head supplier’s products have a lifespan of more than 50,000 hours, a difference of more than 5 times.
In addition, non-standard white brand motors lack perfect after-sales service. Once a fault occurs, the supplier cannot provide timely technical support, resulting in extended equipment downtime.
An automation company reported that after using white-brand motors, equipment downtime exceeded 10 hours per month. However, using products from leading suppliers, downtime was less than 1 hour per month, and production efficiency increased by 15%.
Future trend: technological iteration direction of low-voltage servo motors.
Industry experts predict that future technology iterations of low-voltage servo motors will develop in the direction of high precision, low energy consumption, and intelligence.
In terms of high precision, the repeat positioning accuracy will be increased from the current ±0.01 mm to ±0.005 mm to meet the needs of higher-end scenarios.
In terms of low energy consumption, the energy efficiency of the motor will be upgraded from the current IE3 standard to the IE4 standard, reducing energy consumption by more than 10%.
In terms of intelligence, the motor will integrate sensors and Internet of Things technology to achieve remote monitoring and fault warning, and improve the operation and maintenance efficiency of the equipment.
The R&D director of Changzhou Chuangwei Motor said that the company is already developing a new generation of low-voltage servo motors that integrate temperature and vibration sensors, which can monitor the operating status of the motor in real time and provide early warning of failures.
It is expected that mass production products will be launched in 2027 to meet the market’s intelligent needs.
