Quelle est l'applicationA European manufacturer specializes in automatic polishing and grinding machines for metal and aluminum components. These machines are widely used in surface finishing processes where surface consistency, low vibration, and long-term reliability are critical to final product quality.
In recent years, the customer began upgrading their equipment to meet higher standards for automation and surface quality. During this process, they found that traditional brushed motors could no longer meet the requirements for stable speed control, continuous operation, and low maintenance.
As a result, the customer started looking for a brushless motor solution specifically designed for polishing and grinding applications.
During technical discussions and on-site testing, the customer identified several key challenges:
Speed instability under load
When the polishing wheel contacted the workpiece, load fluctuations caused noticeable speed drops, leading to uneven surface finish.
Vibration affecting surface quality
Mechanical vibration from the motor directly translated into visible polishing marks on the workpiece.
High temperature rise during continuous operation
The machine was designed for long production cycles, requiring S1 continuous-duty performance.
Espace d'installation limité
The motor needed to be compact while still delivering sufficient torque for polishing operations.
High maintenance frequency
Brush wear and frequent servicing increased downtime and operating costs.
After analyzing the application conditions and operating requirements, BG Motor recommended the BG60BLDC brushless motor, configured to match the required output speed and torque of the polishing machine.In addition, we also have 80mm, 90mm, 110mm, 130mm and other sizes of motors for selection.
Modèle de moteur: BG60BLDC 24V 48VDC High-speed Polishing Machine Motor
Puissance: 200 à 400 W
Tension nominale: DC de 48V
Vitesse du moteur: 3,000 RPM
Cycle de service: S1 Continuous Operation
The BG60BLDC motor was selected based on several critical application advantages:
Stable speed under load
Electronic commutation and closed-loop speed control ensure minimal speed fluctuation during polishing contact.
Faible vibration et faible bruit
The brushless structure significantly reduces mechanical friction, improving surface finishing consistency.
High efficiency and low temperature rise
Suitable for long working cycles without performance degradation.
Conception compacte avec une densité de puissance élevée
The 60 mm motor size fits well into space-limited polishing machine structures.
Longue durée de vie et faible entretien
The brushless design eliminates carbon brush wear, reducing downtime and maintenance costs.
After sample testing and parameter optimization, the customer confirmed a clear improvement in surface quality, operational stability, and thermal performance compared to their previous motor solution.
After the polishing machine entered actual production use, the customer reported:
More consistent surface finish quality
Reduced vibration and operating noise
Stable motor temperature during long production cycles
Improved overall equipment reliability
Réduction de la fréquence de maintenance et des coûts d'exploitation
The BG60BLDC motor was successfully adopted as a solution standard for the customer’s polishing and grinding equipment platform.
