Efficient 1.1 to 90kW motors qualify for
allowance
Nord Gear has launched a range of energy saving geared motors that not only consume significantly less power, but are on the DETR's energy technology list and qualify for Enhanced Capital Allowances
The Climate Change Levy has brought energy into even greater focus It is also widely understood that the cost of ownership of an electric motor has little to do with its purchase price and everything to do with its energy consumption

The Posicon allows users to program relative or absolute positioning, synchronising, gearing and S-ramp movement profiles.
Now, Nord Gear has launched a range of energy saving geared motors that not only consume significantly less power, but since they are on the DETR's energy technology list, they also qualify for Enhanced Capital Allowances under the UK Government's tax rebate scheme.
The EFF1 AC induction motors range from 1.1kW up to 90kW and when coupled with a helical bevel gearbox as opposed to a helical worm box, savings achieved can be up to 40%! The motors are high efficiency models, while the helical bevel gearboxes provide over 20% additional torque for their size, or to put it another way, require reduced motor power to meet the same duty.
Calculations made by Nord for one case study show that using an EFF1 motor with a 3.0kW helical bevel box (rather than the usual 4.0kW worm box), increases torque from 2260Nm to 2388Nm.
Running at a fixed speed of 12 rev/min, motor power is reduced immediately by 25% thanks to the motor/gearbox configuration alone.
Nord's 3kW EFF1 motor shows a 3.2% higher efficiency compared to the 4kW EFF2 motor that would have been required.
Over a measured 8000 hours operation, the energy cost saving is ?527.00.
Added to this, the use of the helical bevel box gives 5.67% greater torque, which equates to 5.35% reduced motor power, realizing a further saving of ?82.00.
The total operating cost saving over 8000 hours is therefore ?609.00.
In addition to this, by claiming under the ECA, the tax saving in year one is a further 30%, which equates to ?182 on the 3.0kW EFF1 motor.
Nord EFF1 motors and helical bevel gearboxes are available from the company's new 25,000 ft2 manufacturing facility in Abingdon, Oxfordshire.
