Q: I'm currently using your V series three-phase AC gearmotors with variable frequency drives in the machines that I build. I am interested in upgrading to the newer K2S series. What kind of performance differences or new features should I expect?
A: There are a number of performance improvements and features introduced with the K2S series three-phase high torque AC gearmotors which were not introduced with the V series before. For the K2S series, Oriental Motor focused on improving efficiency as well as motor performance when used with inverters or variable frequency drives.
The new K2S series uses specialized components and an optimal magnetic design to improve power conversion efficiency up to 73%. Because of this increased efficiency, we are able to remove the fan from our motor case and offer increased torque output in a shorter case length. Therefore, the K2S series can provide more torque, and it's smaller and lighter than the V series.
Power consumption is reduced up to 10% with the K2S series compared to V series (90W, 1/8HP) which translates to cost savings.
Speed stability and performance characteristics with the K2S series have vastly improved from the V series. Even when dealing with changing load conditions, the motor speed will not fluctuate as much as the V series.
The K2S series motor performance with inverters or variable frequency drives have also vastly improved; allowing a wider recommended speed range than ever before from 3~120 Hz for the round-shaft and parallel-shaft geared type (up to 80 Hz with right-angle geared type). This is an increase in speed ratio from 12:1 to 40:1. Speed stability with inverters/VFD's have also improved.
We have also adopted creep-free bearings in the K2S series round-shaft motors in order to improve high speed performance.
For the K2S series, we have also added some features and options for customer convenience. We have adopted a new slimmer, rotatable terminal box with a higher IP66 drip-proof rating (compared to IP54 on the V series) designed to make wiring even easier. With this new terminal box, you can change the direction of the cable outlet to 4 different positions. Imperial or metric shaft options are also available. We have also adopted stainless steel screws on the motor case.
Last but not least, the K2S series adopts a newer hypoid right-angle gearhead which increases permissible torque, radial load as well as axial load. The V series did not offer a right-angle gearing option. Parallel shaft geared options are standard.
