Features
Achieves "demodulation-less" motor control that does not stop even with a high load or rapid acceleration/deceleration is applied, providing smooth operation with a resolution of 200,000 P/R.
The simple structure of the resolver also contributes to durability against the outside environment. Robust manufacturing supports a motor drive with extremely stable accuracy in harsh environments such as heat, dust, shock and vibration.
Benefits of Resolver Servo Control
1. High Torque Functionality: No demodulation margin required with servo control
Servo control via resolver eliminates the need for a demodulation margin and maximizes available torque. A usable torque 2-3 times more than from conventional products.
2. Low current consumption and low heat generation: Torque controlled with minimal current
Torque control is performed with minimal required current, reducing power consumption and allowing for current to be cut while on stand-by. Contributes to the energy efficiency of your overall setup.
3. High accuracy: 200,000 P/R resolution
Achieves a resolution of 200,000 P/R, repeatedly providing a high level of positional accuracy and smooth drive.
4. Environmental Resistance: Resistant to dust, oil, heat, shock, and vibration disturbances
The resolver is simple in structure and is resistant to disturbances such as dust, oil, heat, shock and vibration.
5. Miniaturization: demodulation-less and no torque margin required
A torque margin is not required given a lack of demodulation. This leads to a smaller motor size.
6. Contributes to fewer components: Gear-less, simplified cooling system, and simplified vibration control
Gear-less (decelerator), simplified cooling measures, and simplified vibration control (dampers). Helps reduce cost and design a more efficient use of space.
7. Low noise and vibration: drive control that responds to load
This device can minimize noise and vibration by providing drive control in response to the applied load.
