EnviroStart TM Motor Energy Controls

• 70% of all electrical power consumed is by electric motors. EnviroStart Motor Energy Controls (MECs) work with any fixed speed single or three phase electric motor, maintaining its speed whilst providing energy savings of up to 40%.
• The EnviroStart MEC constantly adjusts and aligns the power supplied to the motor to match the torque load being placed on it at any moment in time, with a 5µs response time (200,000th of a second).

Optimisation of power consumption in relation to load demand

Saves energy, reduces running costs, reduces related CO2 emissions

Controlled Soft-start and optional Soft-stop

Reduces motor and transmission stress extends life, reduces maintenance

Protection from damage caused by stalled rotor or phase loss

Greater reliability, reduces unplanned downtime risks, prolongs motor life

Detection of phase imbalance in the motor

Provides early detection of motor failure, reduces unplanned downtime

Low-current line contactor operation

Prolongs contactor life, reduces unplanned downtime risks

Reduction in winding heat

Prolongs motor life

Reduces start / stop shock to
both load and transmission system

Prolongs motor and
transmission life, reduces maintenance

Elimination of Star Delta contactors

Reduces maintenance costs

Option to have the line contactor,
(if retained in circuit), to be switched in and out in a zero current condition

Eliminates spark degradation of the contacts, giving increased contactor life

Virtual elimination of motor
failure through winding burnout caused by stalling, over current, over voltage and complete power or phase loss

Prolongs motor life, reduces risks of unplanned downtime and associated costs

Automatic localised power factor improvement

Increases available power on site, reduces incidence of KVA surcharges

Optional remote control and motor fault alarm capability

Enables quick response and reduces the risk of damage

Reduced motor noise through reduction in stator winding harmonics and improved magnetisation efficiency

Provides a quieter working environment
