Leroy Somer's new LSPX/FLSPX range of three phase electric motors offers unparalleled safety in a reliable and cost-effective package for applications where dusty atmospheres present a high risk of explosion Specifying LSPX or FLSPX motors will also ensure that operators of such installations - including bulk material silos - are prepared for the European Union ATEX directive when it comes into effect in August 2003

The new Varmeca is a motor with some simple but clever circuitry in the terminal box and a large knob on the outside with which to control the speed.
No coincidence that the motors are green
As the technology of motors, bearings, ventilation and design techniques continue to improve so will the efficiency of electric motors; Leroy Somer is determined to stay ahead in the race.
The ATEX Directive 94/9/CE will set higher standards of protection for equipment including electric motors used in explosive atmospheres.
It will apply to existing as well as new installations, and installing ATEX-compliant motors will ensure that serviceable equipment does not have to be replaced in 2003.
LSPX/FLSPX motors have been designed and constructed to prevent them being a possible source of ignition in an potentially explosive dusty atmosphere.

Leroy Somer introduces the new FCR range of Brake Motors with power ratings from 0.25 to 132KW, a simple, inexpensive but reliable solution for stopping machinery quickly.
Floor cleaner motor cost cut by open frame design
When rotary floor cleaning machine manufacturer Truvox was developing its new Orbis range, the company turned to Leroy-Somer for the heart of the machine - the motor.
They are painted bright orange to distinguish them from conventional motors.
The whole LSPX/FLSPX range is rated IP65, the best protection against ingress of dust, ensuring that particles cannot enter the motor.
The surface temperature is also guaranteed not to exceed 125C, the lowest temperature at which any cloud of material from cereal dust to sugar could ignite.
Both the LSPX and FLSPX feature highly effective sealing (especially around the output shaft), cable glands, vibration-resistant terminal connections, corrosion-resistant casing and Class F insulation.
The FLSPX also has an anti-spark terminal box, a highly corrosion- resistant body and cast iron end shields and terminal box.
Because the FLSPX and LSPX are modified versions of standard Leroy-Somer motors, the output shafts are standard sizes.
The LSPX is available in standard frame sizes from 63 to 225mm, with power ratings between 0.09 and 37kW.
The single speed version is available with 2, 4, 6 or 8 poles, while a dual speed pole-change version can be supplied with 2/4, 4/6, 6/8 and 6/12 poles.
The FLSPX is available in frame sizes from 80 to 355mm with power ratings between 0.18 to 400kW.
Single or dual speed versions are available, with the same pole options as the LSPX.
Variable speed control, FAP brakes and winding and drive end bearing temperature probes are available as options for both the FLSPX and LSPX.
The new Leroy-Somer range of hazardous area motors provides a safe and cost-effective solution for equipment such as conveyors, elevators, dryers, fans and blowers used in installations with potentially explosive atmospheres including grain stores, sugar terminals, dockside handling facilities and fertiliser bulk stores.
