Industrial drives motor control
Without being aware of it, people probably walk by and even use several LEM sensors each day. Sensors are present in elevators, forklifts, machines tools, printing machines and in all equipment using industrial drives on motors for efficient control, regulation, energy saving and comfort.
Drives control requires reliable and accurate current measurement to enable engineers to develop systems with isolated current measurement directly on the motor phases.
Main applications for Drives
The current sensors are used to measure the constantly varying current in order to feedback for control purposes. This leads to an accurate adjustment of equipment operation. With a machine tool, the current flow increases abruptly when the tool starts working on the part to be machined. The better and faster the feedback signal, the smoother the control of equipment information.
Typical applications for drives sensors include:
- Lifts
- Escalators
- White goods
- Cranes
- Wheel Chairs
- Forklifts
- Electric door opening systems
- Robots
- Pumps
- Steel Mills
- Machine tools (Printing paper, textile, plastic)…
