About Company

Wenvor Technologies Inc. was formed in 1992 and was primarily focused on solar power in the early years. In 1995 we embarked on designing and manufacturing a rugged wind turbine that could withstand the rigors of the extremes in the Canadian climate. 1996 brought about the first installation at what is now called the Wind Energy Institute of Canada at North Cape, PEI.

We have made many design changes to that original concept. We now manufacture both a single phase and a three phase unit producing 30kW. The original fibreglass blades have been replaced by an optional carbon composite design providing lighter weight and increased rigidity. The main frame strength was improved for our cold weather conditions by using high quality ductile cast iron. Recent upgrades involved the addition of soft start controls and optional power factor correction.

We have other R&D projects underway with several universities including the University of New Brunswick, University of Guelph and the University of Waterloo. Tests have been recently run utilizing a new blade design that looks promising to be able to increase power production from lighter wind speeds.

A new series of 3 phase generators manufactured for us by Baldor has just been released for sale as well as new state of the art wind turbine controls manufactured by GE Digital Energy.

Turbine Blades

Turbine blades are carbon composite with aluminum tips and internal copper cable for lightning protection. Blade diameter is 10 metres.

Pitch Regulation

Input shaft speed is approximately 120 RPM.

Turbine has automatic, rugged mechanical 2 stage pitch regulation. First stage has sharp angle of attack to start the turbine in slow wind speeds and in cold temperatures will keep the gearbox oil warm. Second stage brings the RPM to desired speed for power production.

Over speed controls positions blades in "stall" to limit top kW and RPM. output.

Pitch angles and preload are set at the factory. Final adjustments can be easily re-set in the field if the wind conditions dictate the need for individual site adjustment.


Heavy-duty gearbox provides a service factor of 3 .Synthetic oil is used for extremes in temperature and for long life.


CSA approved automatic control system will connect to the grid for Net Metering as per regulations outlined by Hydro One and other utilities. All controls are provided with individual and full test reports to satisfy ESA inspection. Optional controls for stand-alone, battery charging, or wind diesel sites are available.


Standard tower lengths are 24 and 30 metres. Tilt-up towers raise and lower the tower easily for safe maintenance at ground level. Gin (lift) pole and all guy wires, turnbuckles and shackles are provided. All tower and tail vane components are hot dipped galvanized for corrosion protection. Ductile cast iron and steel castings are primed and protected with corrosion resistant enamel.


Upwind turbines manufactured by Wenvor Technologies Inc. in Guelph, Ontario are 30 kW three and single - phase machines.

A 37.5 KVA, 600 V to 240 V step down transformer is provided for single phase systems.

Induction generator voltage is 600 V 60 Hz for both single and three phase generator systems. 50 Hz generators and controls can be provided. Nominal generator RPM is 1800. Generator has automatic re-set protection for over heating conditions.
