Brushless Motors

Whether it’s high torque 4-pole DC-Servomotors, highly efficient flat DC-micromotors, or compact slotless motors, FAULHABER specializes in getting the most performance out of the smallest package. Due to their design FAULHABER brushless motors are predestined for heavy duty servo applications with frequent overload conditions as well as for continuous duty applications where maximum operational lifetime is required.

Brushless DC-servomotors: 2-pole or 4-pole?

FAULHABER high precision 2-pole brushless DC servomotors are three phase ironless motors that have a wide speed and torque range. They are ideal for mid- to high-speed applications requiring smooth speed control, high efficiency, and long operational lifetimes.

For highly dynamic servo applications requiring very high torque in the most compact dimensions, the FAULHABER BX4 and BP4 series 4-pole, DC-servomotors are ideal. Their robust design with very few parts and no glued components means that they are extremely durable and well suited for harsh ambient conditions such as extreme temperatures and high vibration and shock loads.

FAULHABER brushless flat DC-micromotors are 3-phase, slotless, axial flux gap motors with a rotating back iron. They have a much higher efficiency than other flat brushless motors and their rotating back iron provides a high rotor inertia that is ideal for applications requiring low torque ripple and very precise continuous speed control.

FAULHABER also offers a range of 2-pole brushless motors with a cylindrical rotating back iron sometimes referred to as ironless external outrunner motors. What sets the FAULHABER motor apart is the slotless design, which eliminates the cogging torque. The high inertia of the rotor makes these motors ideal for continuous duty applications that require very precise speed control. These motors also have integrated speed control that can be configured for different speed profiles.
