Stepless is the technology invented and developed by CMZ for low speed applications.
Through the closed loop control, a stepper synchronous motor can be controlled with modulated current by:
- eliminating any problem due to the step loss
- reducing the motor temperature
Compared to the brushless solution, on the same motor size the Stepless technology provides higher torque at low speed. This makes it most suitable for a wide variety of low speed applications.
ISD is our stepless integrated servo drive for decentralized architecture, featuring:
- internal programmability
- CANOpen, PROFIBUS, MODBUS RTU protocols
- usability with all master controllers using CODESYS.
It is available in 3 different models from 4,6 Nm to 12 Nm.
| Model | Holding Torque (Nm) | Flange (mm) | Total Length (mm) |
|---|---|---|---|
| ISD 1281 | 4,6 | 86 | 186 |
| ISD 1271 | 8,5 | 86 | 224 |
| ISD 1261 | 12 | 86 | 262 |
