The DDCT motor combines the field-proven and power dense AC laminated frame RPM AC motor with a high-performance interior permanent magnet (IPM) salient pole rotor design. The motor is paired with an adjustable speed drive. A direct drive solution offers the benefit of variable speed control while eliminating the cost and maintenance required for traditional gearbox or belted solutions. The fan couples directly to the motor and is controlled by an AC drive to provide reduced maintenance, energy consumption and quiet operation.
As few as three attributes (motor horsepower, fan speed and air velocity over the motor) are required to calculate a DDCT package. The Cooling Tower Wizard output identifies a stock motor and drive solution or a custom designed package based on application data. Essential product details including stock product number, frame sizes, current and motor efficiency are provided. Additional product details are available for download in spreadsheet form, including performance data, noise levels, motor and drive dimensional drawings and detailed annual cost savings estimation.
The Annual Operating Cost Analysis tool estimates yearly cost savings between a new direct drive solution and traditional gearbox or belted equipment. For an accurate estimation, most fields are editable to customize the expected operating conditions. The analysis tool empowers users to properly size and select a motor and drive solution for cost savings and performance.
