VS Drives and motors for elevator market!

Control Techniques and Leroy-Somer, both part of Emerson Industrial Automation, are displaying their range of variable speed drives and a new permanent magnet motor specifically for the elevator market at October’s Interlift 2015 inAugsburg (D 13-16 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.

Combined with the E200 or E300 drives ( STO according to EN61800-5-2:2007) and the E27 motor, the Brake Control Unit (BCU) is a contactorless solution offering two mains functions; the management of the brakes supply during normal operation and the management of the rescue (according to EN81-20 / 50). The two independent contactors cutting the line between the drive and the motor along with the two cutting the line of the brakes supply can be removed. The benefit is the removal of the noise from the elevator shaft, along with the direct savings in components and wiring.

John Orrells, elevator market strategic manager for Emerson Industrial Automation, said: “The E200 and E300 drives, combined with the E27 motor and Brake Control Unit (BCU), offer a complete solution for our elevator customers.
“These products have been developed after extensive market research and feedback from our customers. Our research has directly influenced our engineering and design program, resulting in drives and motors designed specifically to operate together.
“This provides an additional guarantee of high performance for the customer, with simplified maintenance and after-sales service, while meeting the requirements of the elevator market.”
