Starting with Energy Saving Motors
Reducing CO2 Emissions with Brushless Motors
By adopting an energy-saving motor for speed adjustment such as transportation, stirring, and winding, it is possible to reduce power consumption and CO 2 emissions. The brushless motor is a speed control motor that combines a compact, high-efficiency motor with a hall sensor and a dedicated circuit (driver) that performs feedback control.
The Effects of Using a Brushless Motor
Annual power consumption (compared with output 60W)
(kWh / year)
|CO 2 emissions
(kg / year)
(SGD / year)
● Daily drive time 12h, annual operating days 300 days, power -CO 2 emission conversion coefficient 0.519kg-CO 2 / kWh, power tariff 0.28 cents / kWh
●The usage conditions are as follows; AC motor: output 60W , Single-phase 200V, 60HZ brushless motor: BMU series, output 60W
Reduction of power consumption: 165 kWh/year
CO2 emssions: 86 kg/year, 37% reduction
More Efficient than Inverter Control
Brushless motors use permanent magnets in the rotor, suppressing rotor secondary loss. This results in a roughly 26% reduction in power consumption compared to a three-phase induction motor for inverter control*. This helps the equipment to save energy.
* When Output Power is 90 W
A Smaller, Lighter Motor Means Fewer Natural Resources
Brushless motors with built-in permanent magnets are both slim and high-power. For example, compared to a three-phase induction motor of frame size 90 mm, their total length is 84.6 mm shorter. This contributes to equipment downsizing and the use of fewer natural resources.
A huge variety of motors is available, from ones that offer easy speed adjustment with a dial to ones that offer position control and network control. Select the motor that best suits the application at hand.
