Introducing ElectroCraft's new MobilePower™ MPW52 wheel drive, featuring a high torque-density brushless DC motor with integrated single-stage planetary gearbox and wheel assembly.

ElectroCraft's MPW52 integrates a 14-pole Brushless DC motor with a heavy-duty, single-stage planetary gearbox mounted inside the hub of an aluminum wheel with polyurethane tread. Designed for mobile platform traction systems with optional encoder feedback to support positioning capability and electromagnetic brake to hold position when power is removed. The MPW52 combines optimum performance with high-efficiency, quiet operation and long life.

ElectroCraft MobilePower™ MPW series wheel drives feature an integrated design that provides increased performance and reliability at an affordable price compared to traditional motor/gearbox/wheel combinations. As with all ElectroCraft products, the MPW series wheel drives are customizable to meet specific application requirements.

Features:

  • Smooth, efficient motion
  • Compact, lightweight, durable and highly reliable integrated design
  • Powerful starting torque:
    • Peak torque up to 12.4 Nm
    • Continuous torque up to 6.1 Nm
  • Configurable or completely customizable designs
    • Motor, gearbox, wheel, brake, encoder, cabling
  • Typical applications:
    • Automated Guided Vehicles
    • Autonomous Mobile Robots

For a complete solution, the MPW52 is compatible with ElectroCraft's Universal and PRO Series drives.
