‘Re-invented’ fan motor cuts energy use by up to 80%
Published:  30 September, 2015

QM Power is offering a two-year warranty on its new motors and is introducing a financing scheme that will allow refrigeration users to retrofit the Q-Sync motors to their equipment at no cost, in exchange for sharing their energy savings with QM Power.

QM Power says that its Q-Sync motors are the most efficient fan motors on the market

Initially, the company is offering the new motors in ratings from 9–12W for use on 95–140V supplies, but plans to expand the range to include ratings up to 50W and versions that will operate on 240V supplies. It is also working on multi-speed and variable-speed versions.

Another QM technology – called PPMT (Parallel Path Magnetic Technology) – uses innovative flux-concentration topologies to deliver high power and torque densities, and efficiencies for motors, actuators and generators. Magnets are arranged to create parallel flux paths and field coils to direct their magnetic flux. QM claims that the result is four times the force from a given electrical input using the same electromechanical components. PPMT actuators can stay in a “locked” position without needing additional electrical input.

Since it was founded nine years ago, QM Power has received more than $20m in venture funding, contracts and grants. It is subcontracting the manufacture of its motors, with some initial production being carried out in China.
