Servo Motors (Motor Only)
Tuning Free Servo Motors

The NX Series tuning free servo motors are capable of highly accurate control with easy operation, similar to stepper motors. These servo motors are specialized for high-response, high-precision positioning. As a motor capable of accurate rotation angle and speed control it can be used for a variety of equipment.
- Tuning Free
- Compact and High Power
- Wide Variable Speed Range
- Standard or Planetary Geared Type
- Electromagnetic Brake Types
- NX Series Driver Required*
Hybrid Servo Motor / Stepper Motors

These products use our AlphaStep closed loop technology to maintain positioning operation even during abrupt load fluctuations and accelerations without hunting or gain tuning. The rotor position detection sensor monitors the rotation speed and amount. When an overload condition is detected, it will instantaneously regain control using the closed loop mode. When an overload condition continues it will output an alarm signal, thereby providing reliability.
Using energy saving technology provides lower motor heat output with up to 47% less power consumed. Advanced driver technology provides low vibration along with 2 driver types depending on your system configuration. Use the MEXE02 data setting software for easy set up and monitoring.
- Absolute Mechanical Encoder or Resolver types
- No Hunting or Gain Tuning
- High-Efficiency
- Wide Range of Geared Types
- Electromagnetic Option
- Matching Driver (Built-in Controller or Pulse Input) required.
