Pancake-style Direct Drive Rotary Motor Combines Value and Performance

When it’s time to specify a rotary motor, it can be difficult to find a unit that provides both high performance and value. Even if you find a motor with characteristics you require, it may not fit in designs with limited axial space. One way to overcome these difficulties is to choose a direct drive motor with a flat, pancake-style design. Akribis Systems’ AXD Series iron core motor is one such example, featuring exceptional torque performance that outmatches many competitive devices and delivers excellent precision at an attractive price.

The AXD motor uses direct drive technology, which means it connects directly to the load, incorporates a large number of poles and takes advantage of Lorentz force to deliver high torque even at low speeds. For example, the AXD torque ranges from 0.9 Nm continuous, 2.6 Nm peak for an 80-mm diameter unit to 250.6 Nm continuous, 648.9 Nm peak for a 400-mm diameter unit. These torque figures are exceptionally high for motors of their respective sizes, resulting in high torque densities.

They are also significantly better than many comparable units. For example, one particular AXD model exhibits 10.0 Nm of peak torque, which is 70 to 155 percent better than competitive motors of the same size, and its 3.4 Nm of continuous torque is 70 to 240 percent better than the same size competitive motor.
