Performance of parallel fan-powered terminal units with electronically commutated
The versatility of the electronically commutated
drive roller with its compact integral 24 VDC motor, electronics and gears, makes the planning, construction and operation of systems much simpler.
Other features include: dehumidification mode to help manage moisture control in the building, dual air filtration to eliminate particulates, and high efficiency forward curved electrically commutated
fans to optimize air flow.
He added that four other wanted persons turned themselves to security authorities in response to the amnesty issued by the Ministry of Interior and to have their penalties be commutated
This improved pump performance is based on an innovative hydraulic design, combined with electronically commutated
(EC) brushless motor technology.
The two mechanically commutated
DC motors, with output powers of 200 and 250 watts, are protected on the commutation side with sealed aluminum housing, the Fall River, Mass.
Voltage Sags Mitigation with an Integrated Gate Commutated
Thy Based Dynamics Voltage Restorer" Harmonics and Quality of Power proceedings.
The permanent magnet, electronically commutated
8JS three-phase synchronous motors are designed for applications requiring good dynamics and positioning precision.
Abstract: The speed control of an electronically commutated
synchronous motor with permanent magnets on the rotor, controlled by the stator voltage with modulated (PWM) converter is presented in this paper.
High-efficiency fan motors have been added to the cases and, where applicable, electronically commutated
motors that demand 53% less energy have been included.
Maxon's new "EC" series of brushless motors are electronically commutated
enabling extremely long motor life.
NovaTorque is a producer of Electronically Commutated
Permanent Magnet (ECPM) motors that deliver the superior energy efficiency of permanent magnet motors at price points more comparable to the common AC induction motor.
As for the previous CRC units, also the new models come standard with a dynamic humidity and temperature management system (Evolution control), electronically commutated
fans and DC inverter compressors which ensure large energy savings at partial loads.
2011a and 2011b) measured airflows, pressures, and power consumption of FPTUs with permanent-split capacitor (PSC) motors and electronically commutated
motors (ECMs), respectively.
(EC) fan motors are also available as an option.
