New High Speed, High Torque AC Spindle Motor &
Servo Amplifier Boost Machine Tool Productivity

SANMOTION S

March 22, 2013


SANYO DENKI CO., LTD. has developed the "SANMOTION S" servo system combining an AC spindle motor with an AC servo amplifier. The AC spindle motor will be available in two rated output levels: 3.2 kW and 4.5 kW. The servo amplifier's output capacity is 150 A.


This series offers high-speed rotation and large torque at low speed, making it ideal for spindle motors on the machine tools that require high-accuracy synchronized tapping with the feed shaft. The SANMOTION S will help improve the productivity of your equipment.


SANMOTION S

Features

1. High Torque and High Speed

The SANMOTION S delivers 1.5 times more torque and as much as 1.9 times higher rotational velocity than our conventional models.*1 This servo system is great for both low speed heavy cutting with high torque and high-speed milling.*2

2. High Speed Response

The response speed has been increased to 2.5 times the level of our conventional models.*1 Even in the medium speed range this product shows only a modest decline in response speed. This allows spindles for machine tools to achieve high-accuracy synchronized tapping*3 with the feed shaft.

3. High Acceleration

The SANMOTION S provides up to 4.5 times higher maximum angular acceleration than our conventional models.*1 Short acceleration and deceleration time—a transmission time of 500 ms or less*4— will significantly reduce your equipment's processing cycle.
*1. Our conventional models: S4 servo motor, SZ servo amplifier
*2. A machining process of using rotary cutters to remove material from a workpiece's surface
*3. A machining process of cutting threads
*4. Rated output 4.5 kW, JL=0
