AVAILABLE POWER RANGE

110 kW to 135 MW

Built to Withstand Industrial Environments.

Available with IP55 and IP66 protection ratings, Imperium motors are designed to resist dust, moisture and harsh environmental conditions commonly encountered in mining, utilities and heavy industrial facilities.

Why it matters:

✓ Dust protection

✓ Water ingress protection

✓ Suitable for harsh environments

✓ Increased operational reliability

Both Available

Class F & Class H Insulation

Available with Class F or Class H insulation, the motor can be specified to suit the thermal demands of your application. Higher insulation classes provide additional protection against heat, improving reliability and extending motor life.

Why It Matters:

A well-insulated motor is better equipped to withstand the thermal stresses encountered during everyday industrial operation.

Longer Motor Life

Heat is one of the primary causes of insulation ageing. You are guaranteed increased thermal endurance, helping to protect the winding system and extend the motor's operational lifespan.

Reduced Downtime

Reliable insulation helps minimise the risk of heat-related winding failures, reducing unexpected breakdowns and keeping equipment operating when it matters most.

Reliable Industrial Performance

Class F & H insulation are well suited for demanding industrial environments, providing dependable thermal protection during continuous operation, variable loads and elevated ambient temperatures within its design limits.

Lower Lifetime Costs

By helping reduce maintenance requirements, unplanned repairs and premature motor replacement, this feature contributes to a lower total cost of ownership over the motor's service life.

One-Year Warranty.

The Imperium range of Medium and High Voltage motors is backed by a 1-year warranty, providing added confidence in the quality and reliability of your investment. Manufactured to deliver dependable performance in a wide range of industrial applications showcasing Electromote's commitment to product quality and responsive technical assistance.

✓ Added peace of mind

✓ Confidence in Product Quality

✓ Reduced ownership risk

✓ Reliable Technical Support

TECHNICAL SPECIFICATIONS

Multi Voltage

Available in 3.3kV, 6.6kV, 11kV and 13.8kV, the Imperium range integrates seamlessly into medium and high voltage electrical systems used throughout mining, utilities and large industrial facilities.

Vacuum Pressure Impregnation (VPI)

A motor's windings are constantly exposed to vibration, heat, moisture and contaminants. Electromote motors use Vacuum Pressure Impregnation (VPI) to completely seal and protect the stator windings.

Unlike conventional dip varnishing, VPI ensures complete resin penetration throughout the winding, creating a stronger and more durable insulation system.

Fully Processed Lamination Steel (FPLS)

The magnetic core is the heart of every electric motor. Electromote motors are manufactured using Fully Processed Lamination Steel, a premium electrical steel specifically designed to reduce magnetic losses and improve overall motor efficiency.

The result is lower operating temperatures, improved efficiency and reduced energy consumption throughout the motor's lifetime.

The Right Speed Starts with the Right Pole Configuration.

Every industrial application operates differently. Some require high-speed performance, while others rely on slower, high-torque operation. Available from 2 to 24 pole configurations, allowing precise speed selection for everything from high-speed compressors to low-speed mills, crushers and heavy process equipment.

Fewer poles = Higher speed
More poles = Lower speed, higher torque

Speed Isn't Everything.

The fastest motor isn't always the best choice.

Selecting the correct pole configuration ensures your equipment operates at the intended speed while delivering the torque required by the application. This improves efficiency, reduces wear on mechanical components and helps maximise motor life.

Reliable Continuous Duty.

The correct bearing arrangement is critical in medium and high voltage applications. Depending on the motor size, speed and operating conditions, Imperium motors are available with ball, roller or sleeve bearings to maximise reliability and minimise maintenance.

Cooling Systems

Different applications demand different cooling solutions. The Imperium range is available with TEFC, CACA and CACW cooling systems, ensuring optimum thermal performance across mining, utilities, petrochemical processing and power generation.

TEFC – General industrial applications

CACA – Air-to-air cooling for clean, high-performance environments

CACW – Air-to-water cooling for maximum heat dissipation in high-power installations

TEFC Cooling

Removes excess heat
Protects against overheating, dust and moisture
Longer motor life
Ideal for general industrial environments

CACA Cooling (Closed Air-to-Air Cooling)

Closed-loop air cooling system
No external air enters the motor
Cleaner operation with reduced contamination
Perfect for mining and heavy industrial applications

CACW Cooling (Closed Air-to-Water Cooling)

High-capacity water-assisted cooling
Excellent heat dissipation under continuous load
Stable operating temperatures for high-power motors
Ideal for power generation and critical process industries

APPLICATIONS

No two industries operate under the same conditions, but every operation depends on reliable equipment.

From continuous production lines and critical water infrastructure to demanding mining applications, Imperium motors are engineered to deliver dependable performance where it matters most.
