General purpose flux vector inverters
are low cost
General purpose flux vector inverters fit where a simple low cost drive is needed but with increased torque performance.
The new Lenze Tml and Tmd inverters fit where a simple low cost drive is needed but with increased torque performance The use of advanced sensorless vector algorithms gives superior torque control and regulation, for example where the required speed range is wide or where precise control is needed at low speed

Flexibly drive units led to novel storage system
The flexibility of compact, integrated drive and geared motor solutions and decentralised control across enabled the development of a revolutionary clothing storage and retrieval system.
These inverters cover powers from 0.25 to 7.5kW.
The Tmd range suits 3 phase input whilst the Tml is for single phase up to 2.2kW.
All models feature the unique EPM memory chip, which plugs into the front of the drive.
The chip holds all the drive parameters that can be changed by simply plugging in a new chip, even without powering the drive.
EPM chips can be programmed in a hand-held programmer that also copies chips - a process taking less than 3 seconds.
This easy handling means the time to get started is reduced and downtimes are minimised.
Tml and Tmd inverters are economical but also full of features.
There is 200% starting torque available for 25s and full rated torque to below 1Hz.
Response to changes in load are particularly fast.
The small size saves panel space and makes retrofitting easy - at 5.5kW the inverter footprint fits easily inside an A5 sheet of paper. Request a free brochure from Lenze ...
