Brushless servo motors are those that have windings in the stator and permanent magnets attached to the rotor. No brushes are used. These servo motors provide high acceleration, high torque, and no maintenance. They offer the highest torque-to-weight ratio and can be used in the most precise, demanding applications. Brushless motors are available in both metric and imperial frame sizes, and in both slotted and slotless designs. Brushless servo motors offer the highest torque-to-weight ratio and offer several other advantages:
Higher Output: higher speed and torque control
Low Maintenance: the lack of brushes means that the motor’s lifetime is no longer limited by the brush’s life and there is less of a need for maintenance
Positioning Accuracy: brushless servo motors with positional sensors create a reliable closed-loop system. This ensures high accuracy and rotation repeatability
Compact Size: space-saving design allows them to fit in smaller spaces
Reduced noise: operation at <50dB is typical
Improved reliability: with no brushes to replace, downtown is decreased
Because of the design of brushless servo motors, with no windings in the rotor, they are not subjected to centrifugal forces, and they can be cooled by conduction. All of these factors mean that the motor’s internals can be entirely enclosed and protected from dirt or foreign debris.
Slotted vs Slotless Brushless Servo Motors
Slottedbrushless servo motors provide good balance between torque output, motor constant, efficiency, and manufacturability. They provide high efficiency and high acceleration rates. Slotted brushless servo motors feature benefits such as:
Better acceleration/deceleration capabilities
Lower rotor inertia
Lower cost when compared to slotless motors
Better load to rotor inertia ratio
Slotlessbrushless servo motors are designed to optimize for smoothness and create predictable torque output. They have negligible magnetic cogging which provides improved servo performance and allows for extremely smooth motion even at low speeds. They feature:
Kollmorgen's brushless servomotors offer the highest torque/inertia ratio over a broad range of speeds—including high speed capabilities up to 8,000 rpm for standard designs and up to 70,000 rpm for special designs.
With a design targeted for the most common servo motor features and offering torque ranges from 0.5N-m to almost 16 N-m, VLM delivers all the torque and performance of a servo while helping you control application costs.
