Electric motors are preferable to other motor types in many motor transmission applications. Harmonic Drive offers direct drive and hollow shaft motors that can add substantial value to your manufacturing processes. Trust our decades of experience helping businesses in industries and applications ranging from robotics and medical devices to automotive and aerospace obtain and implement the most innovative precision motion control solutions.

What Are Direct Drive Motors?

Direct drive motors can drive a load without a speed reduction mechanism, making them ideal for applications requiring rapid acceleration. Since they only require low torque to accelerate, they perform well in manufacturing processes characterized by frequent starts and stops.

The benefits of direct drive motors include:

  • Efficiency: Because these motors have lower friction loads and can accommodate partial loads, they are more efficient and can significantly reduce energy costs.
  • Reliability: Direct drive mechanisms feature a relatively simple design and generate minimal backlash, leading to fewer mechanical issues and less downtime.
  • Less maintenance: With fewer components requiring regular service, these motors are easier and less expensive to maintain, resulting in lower long-term operating and ownership costs.
  • Precision: These motors are renowned for their consistent, repeatable performance and exceptional accuracy.

What Are Hollow Shaft Motors?

A hollow shaft motor features an innovative design with a hole in the center that allows the components to pass through the rotational axis. This motor type performs well in various robotics, automation and precision manufacturing applications.

Hollow shaft motor highlights include:

  • Lightweight: These motors are lighter than their solid shaft counterparts, making them easier to install or transport between locations.
  • Space-saving: The compact design allows hollow shaft motors to fit in smaller machinery, conserving essential space within the unit. This feature also provides additional mounting flexibility.
  • Enhanced torque generation: The design of a hollow shaft motor generates extra torque, which supports applications with a higher energy demand.
