Frameless servo motors offer efficient compact solutions for low voltage applications
Parker Hannifin has increased its range of frameless Permanent Magnet AC (PMAC) motors with the introduction of the low voltage K Series. These servo motors are suitable for use in applications where compactness, reliability, precision and cost-effectiveness are critical.
The CE-certified K Series helps simplify machine design as both the rotor and stator are directly implemented inside the system. With low voltage capability starting from 12Vac, the K motor series covers a speed range up to 10,000rpm, and continuous torque to 23Nm.
K Series servo motors are constructed with magnets glued to the rotor, compact copper coils for a shorter size and a large hollow shaft. The series is available in diameters of 32, 44, 64, 89 and 178mm along with three different lengths per diameter and three torque/speed levels per length.
Synchronous PMAC brushless motors occupy as little as a quarter of the space of asynchronous motor technology at the same power rating and offer higher efficiency of between 90 and 95%. In addition, K Series motors give full torque at low-speed, while accuracy is enhanced and vibration and inertia reduced.
Despite being lightweight, K Series motors provide high levels of inherent stiffness and robustness to help ensure accuracy. Natural cooling and maintenance-free operation are further benefits.
