HW250 Horizontal Drive Wheel

Specification of HW250 Horizontal Drive Wheel

Key Features of HW250 Horizontal Drive Wheel

1. Horizontal steering (“horizontal drive”) design
   The wheel pivots/steers along a horizontal axis, suitable for AGV designs where drive units need to steer in-plane.

2. Support for multiple control interfaces
   It supports CANopen, Modbus, EtherCAT, as well as pulse-based control.

3. High-reliability planetary (secondary) gearbox
   Uses a secondary reduction gearbox with good bearing capacity and reliability.

4. External brake & detachable wheel design
   The wheel is detachable and includes an external brake mechanism.

5. Hard-toothed surface gear grinding for the steering mechanism
   The rotary (steering) mechanism uses a gear-grinding process on the tooth surface to achieve higher precision control.

6. Two performance variants (HW250-SM1500-48 and HW250-SM2500-48)

Advantages of HW250 Horizontal Drive Wheel

From those features, here are what the advantages are (or implications) in real-world use:

• High load capacity
  With a carrying capacity of 1,500 kg, this wheel is suited for heavy-duty AGV or material handling applications (e.g. large loads, pallet systems).

• Strong traction
  The rated traction (up to 1,800 N in the higher-power version) means good grip even under heavier loads or in demanding conditions.

• Flexibility in speed and torque
  The two variants allow you to select based on your desired tradeoff of torque vs speed. The higher-power version offers higher torque and marginally higher top speed.

• Precision steering & control
  The use of gear-grinding on the rotary mechanism plus support for precise control protocols (CANopen, EtherCAT, etc.) means you can achieve tight, accurate steering performance — important in tight aisles or for complex motion paths.

• Ease of maintenance
  Because the wheel is detachable and the brake is external, servicing, replacement, or repair of parts is simpler, reducing downtime.

• Reliable and durable mechanical design
  The planetary gearbox, good bearing design, external brake, and careful gear manufacturing contribute to lower failure rates, longer life, and stable performance under load cycles.

• Good range of control integration
  Supporting multiple control buses and pulse-based control gives flexibility in system architecture (e.g. if your control electronics use CANopen or EtherCAT, you can directly integrate).

• Decent speed capability
  Travel speeds up to ~70–75 m/min are reasonable for many industrial material transport applications.

• Compact steering angle
  ±110° of steering gives flexibility while ensuring that the steering mechanisms don’t need to rotate excessively or require very large physical clearance.
