Electric Motors

We offer the full range of Challenge Electric Motors in South Africa.

The Challenge range of three-phase electric motors comply with IEC 60034 standards and are available in IE1, IE2 and IE3 efficiencies.

The motors are approved having fan-cooled, high-grade cast aluminum alloy squirrel caged construction, incorporating engineering grade plastic terminal boxes.

All motors have multi-mount feet and thus can achieve numerous mounting positions.


Three-phase motors

• 2, 4, 6 and 8 pole up to 315kW available complying to IEC 60034,

• IEC 60034 specifies energy-efficiency classes for single-speed, three-phase, cage-induction motors

with 2, 4 or 6 poles. It classifies three classes: IE1 (standard), IE2 (high) and IE3 (premium). For each

class the efficiency is defined for a rated output range from 0.75 to 375 kW. In the European Community

the IE2 class is mandatory for all new motors since 16 June 2011. The IE3 class became mandatory

from 1 January 2015

• Premium efficiency - complying with IE3 efficiency levels according to IEC60034-30

• From frame size 56 to 355

• Manufactured from high grade cast aluminium alloy or GG25 Cast Iron with engineered grade plastic

terminal boxes

• Multi-mount detachable feet as standard

• Full range of mounting positions available

• Voltage ratings of 380v / 400v / 415v

• 50 Hz or 60 Hz rated frequencies

Single phase motors

• Manufactured from high grade cast aluminium alloy with engineered grade plastic terminal boxes

• Fully comply with IEC 60034

• Frames sizes 56 - 100

• Voltage ratings of 110v / 220v / 230v / 240v

• 50 Hz and 60 Hz rated frequencies

• Available with permanent capacitors or as capacitor start – capacitor run
