Product Details

High-Precision Direct Drive & Feedback System

Our 50mm Servo Motorized Roller features an integrated external rotor permanent magnet brushless motor. By removing mechanical gearboxes, we've achieved a streamlined design that minimizes energy loss and maintenance. The standout feature is the inductive encoder (comprising a rotating module and a fixed stator). Unlike traditional Hall sensors, this high-precision chip provides ultra-accurate feedback, allowing the motor control system to monitor power density and manage start-stop cycles with extreme stability.

Engineered for Harsh Industrial Environments

Logistics hubs can be demanding. Our servo rollers are built to withstand the elements. The inductive position encoding utilizes a non-contact induction principle, making it immune to performance degradation caused by dust, moisture, or mud. This ensures 24/7 reliability for cross-belt sorting machines and induction platforms.

Frequently Asked Questions

Q What makes the 50mm Servo Motorized Roller different from traditional motorized rollers?

Unlike traditional rollers that rely on mechanical gearboxes and Hall sensors, our 50mm Servo Motorized Roller uses a direct drive external rotor brushless motor combined with a high-precision inductive encoder. This eliminates gearbox-related energy loss and maintenance, while providing ultra-accurate position feedback and superior start-stop stability.

Q Can this roller operate reliably in dusty or wet logistics environments?

Yes. The inductive position encoding system operates on a non-contact induction principle, which means it is inherently immune to performance degradation caused by dust, moisture, or mud. This makes it ideal for demanding logistics hubs and sorting facilities that require 24/7 uptime.

Q What power and load options are available for the 50mm servo roller?

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 requirements.

Q What is the operating speed and linear velocity range of this servo roller?

The servo roller supports a rotational speed range of 100 to 1500 rpm, which translates to a linear conveying velocity of 1.0 to 3.5 m/s. This wide range makes it suitable for both slow precision handling and high-speed sorting applications.

Q What is the input voltage and insulation class of the roller motor?

The motor operates on a DC 48V input voltage, which is a common standard in industrial conveyor systems. The insulation is rated at Class F, ensuring reliable thermal performance and long service life even under sustained peak torque operation.

Q Is this servo motorized roller suitable for cross-belt sorting machines?

Absolutely. The high-precision feedback system and stable start-stop control make this roller an excellent fit for cross-belt sorting machines and induction platforms. Its robust construction and non-contact encoding ensure consistent performance in high-cycle, high-throughput sorting environments.
