LMDCE573 Novanta IMS – Lexium MDrive / Liberty MDrive NEMA 23 Integrated Stepper Motor, Ethernet TCP/IP, Closed Loop, 3-Stack
The LMDCE573 is the NEMA 23, triple-stack, Ethernet version of the MDrive integrated motor range. It was launched by Schneider Electric Motion as Lexium MDrive and is now manufactured and supported by Novanta IMS as Liberty MDrive. It combines a 57 mm 1.8° hybrid stepper motor with drive electronics, a programmable controller, I/O and an internal encoder. With 171 N·cm of holding torque, the most of the standard-torque NEMA 23 range, it can drive heavier axes than the NEMA 17 models while remaining a single, compact unit connected directly to the plant network.
Reading the LMDCE573 Reference
| Code | Meaning |
|---|---|
| LMD | Lexium / Liberty MDrive, standard hybrid stepper motor |
| C | Closed loop with hMTechnology and incremental magnetic encoder |
| E | Ethernet TCP/IP: EtherNet/IP, Modbus TCP, Profinet IO, MCode |
| 57 | NEMA 23 frame (2.3″ / 57 mm) |
| 3 | Triple-stack motor |
Torque Across the NEMA 23 Ethernet Range
| Stack length | Holding torque |
|---|---|
| Single | 73 N·cm (103 oz-in) |
| Double | 112 N·cm (159 oz-in) |
| Triple (LMDCE573) | 171 N·cm (242 oz-in) |
Power Supply
- Motor/drive supply: +12 to +60 V DC
- Auxiliary logic supply: 12 to 24 V DC, which keeps the controller and encoder position active when motor power is removed
Industrial Ethernet Connectivity
- EtherNet/IP: ODVA conformance checked
- Modbus TCP
- Profinet IO
- MCode OS: programming over Ethernet
I/O and Protection
- Digital inputs: 5 to 24 V DC
- Analog input: 0 to 10 V DC
- Outputs: open collector up to 60 V DC
- Protection: over-temperature, short circuit, transient, overvoltage and inductive clamp
hMTechnology Closed-Loop Control
The encoder-based hMTechnology closed-loop mode provides anti-stall operation, variable current control to reduce heat and energy use, and a torque mode. This lets the stepper behave much like a servo while keeping the simplicity and holding torque of a stepper motor.
Thermal Limits
- Maximum power stage temperature: 85 °C
- Maximum motor temperature: 100 °C
