LMDCE423 Novanta IMS – Lexium MDrive / Liberty MDrive Integrated Stepper Motor, NEMA 17, Ethernet, Closed Loop
The LMDCE423 is an integrated stepper motor from the MDrive family, originally sold as Schneider Electric Lexium MDrive and now manufactured by Novanta IMS as Liberty MDrive. It combines a NEMA 17 (42 mm) 1.8° hybrid stepper motor, drive electronics, a programmable motion controller, I/O and an internal encoder in one compact unit. It connects directly to Ethernet networks, so it suits decentralised positioning axes where cabinet space and wiring must be kept to a minimum.
Reading the LMDCE423 Reference
| Code | Meaning |
|---|---|
| LMD | Lexium / Liberty MDrive with standard hybrid stepper motor |
| C | Closed loop with hMTechnology and incremental magnetic encoder |
| E | Ethernet: EtherNet/IP, Modbus TCP, Profinet, MCode/TCP |
| 42 | NEMA 17 frame (1.7″ / 42 mm) |
| 3 | 3-stack motor length |
Ethernet Communication
- Protocols: EtherNet/IP (ODVA compliant, adapter class), Modbus TCP, Profinet, plus MCode/TCP for programming
- Data rate: 100 Mbps
- EtherNet/IP: explicit and implicit messaging
Closed-Loop hMTechnology
The internal encoder enables closed-loop operation with hMTechnology, which combines the benefits of stepper and servo motors. Encoder functions include:
- Anti-stall: prevents loss of synchronisation
- Variable current control: reduces energy consumption and motor heating
- Torque mode
Electrical and Motion Data
- Supply voltage: +12 to +48 V DC
- Maximum current: 2.0 A
- Microstep resolution: 20 settings
- Motor: 2-phase, 1.8° hybrid stepper, NEMA 17; the 3-stack is the longest, highest-torque length of the NEMA 17 family (31–62 N·cm holding torque across 1 to 3 stacks)
Operating Limits
- Ambient operating temperature: −20 to 50 °C
- Maximum power stage temperature: 85 °C
- Maximum motor temperature: 100 °C
Typical Applications
The LMDCE423 is used for format change and adjustment axes, labelling and packaging machines, laboratory automation, and other compact multi-axis equipment where each axis is controlled directly over the plant Ethernet network.
