RotoVerter Voltage, Frequency Rotary Converter Motor-Generator Systems

Motor-Generator Set with Control Switchgear

APT offers a wide variety of Motor-Generator Sets, Packages and Systems that can be customized to your application and needs. It allows you to use it as a 50/60 Hz convertible power supply. You can also use either a variable frequency or voltage power supply. They can be used for rotary UPS, solving power quality problems, frequency and voltage converters, grid isolation, grid support devices and microgrids.

Motor Generator Converter Set

Advantages

Complete galvanic isolation between the power source and the load via mechanical coupling. This prevents the most extreme over-voltages and surges on the utility side from damaging loads connected to the generator side of the system.
High Available fault current which allows for selective time-overcurrent coordination. This increases the system’s fault tolerance. In other words, the short circuit in one part of the load may not affect other parts of the load. This is not achievable when traditional solid state UPS systems are used.
Motor Starting capability, which is also not achievable when traditional solid state UPS systems are used.
Ability to operate at wide range of voltages (generally between 120V and 15,000V). It can also parallel unlimited number of units to achieve any kW and kVAR output.
Proven industrial, utility grade motor, generator technology and readily available spare parts and motor/generator repair and maintenance facilities.

Limitations

Relatively low system efficiency (around 91%)
Recommended bearing maintenance every 2 years

Motor Generator Converter Set Types & Applications

Rotary UPS

Motor-Generator based Uninterruptible Power Supply Systems remain a golden standard of the Uninterruptible Power Supplies. They are the answer when equipment fails due to power surges, and sudden voltage fluctuations or unplanned power losses is not an option.

Power Conditioning

Complete galvanic isolation between the power source and the load via mechanical coupling. This prevents the most extreme over-voltages and surges on the utility side from damaging loads connected to the generator side of the system.
Ride through upon most single-phase faults and sags and short three phase voltage sags which are milliseconds in duration.
High available fault current which allows for selective time-overcurrent coordination. This increases the system’s fault tolerance. In other words, the short circuit in one part of the load may not affect other parts of the load. This is not achievable when solid state systems are used.
Motor starting capability, which is also not achievable when traditional solid-state conditioning systems are used.
Ability to operate at wide range of voltages (generally between 120V and 15,000V). It can also parallel unlimited number of units to achieve any kW and kVAR output.

Frequency Converters

50/60 Hz frequency converters
60/50 Hz frequency converters
DC to 60 Hz or 50 Hz three phase converters
Variable frequency power source
Variable voltage power source

Frequency/Voltage Stabilizer

Trust APT’s Motor-Generator system when a renewable power source can produce power with unstable frequency and voltage. As a result, it converts this “unstable” power into the utility grade power source with stable voltage and frequency.
