Exro has developed and patented a unique method of “self-optimizing” electric motors and generators to reduce losses in high variability applications. Our first commercial application is wind power, where we are collaborating with numerous turbine makers to convert their existing geared turbines to direct-drive using our Variable Input Electrical Generator (VIEG).
The benefit is an immediate increase in the turbine’s annual output along with a significant reduction in downtime and annual maintenance. In addition to wind power, our technology platform has a compelling value proposition for run of river and marine power, as well as electric vehicles, industrial motors, portable power and other inherently variable applications where reducing losses equates to a material economic benefit.
Exro Technologies Inc., a privately held Canadian Corporation based in Vancouver Canada, is the exclusive provider of the Variable Induction Electrical Generator (VIEG), a unique Direct-Drive Permanent Magnet Generator designed specifically for clean energy applications. Initially targeting wind, Exro’s VIEG eliminates the need for a gearbox— which reduces maintenance issues and eliminates system losses. The VIEG also provides additional increases in energy output along with increased fault tolerance, all without a need for a complete turbine redesign. The installation of the VIEG drives down the cost per kilowatt hour by producing a double-digit improvement in a turbine’s annual energy output (kWh per year) and by decreasing the cost of ownership of the turbine over its lifetime. The company has working prototypes and is currently engaged in testing and validation activities designed to quantify the economic value of the technology in a range of applications.
