❓ Frequently Asked Questions
Q
What makes the 50mm Servo Motorized Roller different from conventional motorized rollers?
Unlike conventional rollers that rely on mechanical gearboxes, our 50mm Servo Motorized Roller uses a direct drive external rotor permanent magnet brushless motor. This eliminates gearbox-related energy losses and maintenance, while the integrated inductive encoder provides far superior positional feedback compared to standard Hall sensors.
Q
How does the inductive encoder improve performance over traditional Hall sensors?
The inductive encoder uses a non-contact induction principle with a rotating module and a fixed stator. This high-precision chip delivers ultra-accurate positional feedback, enabling the motor control system to monitor power density and manage start-stop cycles with extreme stability — performance that Hall sensors simply cannot match.
Q
Can this servo roller operate reliably in dusty or wet logistics environments?
Yes. The inductive position encoding system is inherently immune to dust, moisture, and mud contamination because it operates on a non-contact induction principle. This makes the roller ideal for demanding logistics hubs, cross-belt sorting systems, and induction platforms requiring 24/7 uptime.
Q
What power and load capacity options are available?
The roller is available in three rated power configurations under S2 duty cycle: 200W, 300W, and 400W. Corresponding maximum load capacities are 15kg, 25kg, and 30kg respectively, allowing you to select the right specification for your application's throughput demands.
Q
What is the operating voltage and speed range of the servo roller?
The servo roller operates on a DC 48V input voltage. The speed range spans from 100 to 1500 rpm, delivering a linear belt velocity of 1.0 to 3.5 m/s — suitable for a wide variety of conveying and sorting applications.
Q
What insulation class does this motor meet, and why does it matter?
The motor is rated at Insulation Class F, which supports continuous operation at elevated temperatures up to 155°C. This ensures long-term electrical reliability and safety during sustained high-load operation in industrial conveying environments.
