Elevator Drive And Motor Solution

Control Techniques and Leroy-Somer, both part of Emerson Industrial Automation, an Emerson business, displayed their range of variable speed drives and a new permanent magnet motor specifically for the elevator market at Interlift 2015 in October. The Control Techniques E200 and E300 drives and the Leroy-Somer E27 motor make installing and commissioning elevator systems quick and simple. E200 & E300 have an intuitive user interface which allows easy adjustment via a back-lit LCD keypad and rapid set-up in familiar elevator language and units. Meanwhile, the compact and silent E27 motor offers a completely new design to ease mechanical and electrical installation. A central sheave allows a simplification of the chassis, while also offering full access to the sheave and traction ropes. Equipped with fast connectors for the power, the brakes, the thermal sensor and the encoder, the E27 motor guarantees a quick and reliable electrical connection. Optimum ride comfort is provided by the new drive and motor solution: both E200 and E300 integrate a high resolution multi-step S-ramp for start, run, slowdown and stopping, as well as an ultra-fast current loop for vibration free motor control. Additionally, E300 offers extra levels of ride comfort with direct to floor positioning, an advanced communications interface supporting DCP3/4 and Modbus RTU protocols, short floor operations and on-board data logging capabilities. In association with the E27 motor equipped with optional load cell, ride comfort is improved as the starting torque is adapted depending on the load.
