FAQs

 

Regal PSC motors have connection diagrams on them. Please look on the motor label.

Yes, Genteq ECM products are UL recognized.

Yes, we offer the 142R product for outdoor applications. It is offered in a horsepower rating range from 1/5HP to 1.0HP

Power density is simply the ratio of output power or horsepower to physical size or volume of the motor. There are many factors such as material characteristics and temperature constraints that limit how much power a machine can deliver of a certain size. Different topologies and machine configurations address these limitations in various ways. For example, rare earth permanent magnets produce more flux for their physical size than the magnetic energy (and resultant torque) produced by an induction motor’s “squirrel cage rotor”. As such, a DEC Star® motor can have higher power density than an equivalent rated IM.
The term commutation comes from the world of DC motors. It refers to how current is routed to the right coils, in the DC rotor, at the right time to generate the torque needed by using brushes and a commutator. A commutator is round, mounted on the rotor shaft and has conductive pads on the O.D. on which the brushes rest. Current is conducted from the brushes to the commutator and then to the connected coils as the rotor spins. This term has been carried over to brushless DC motors where the brushes and commutator have been replaced by electronics and a sensor on the rotor shaft. In this case current is still “switched” but by electronics. The term loses meaning in the world of AC motors but still sometimes refers incorrectly to how the AC voltage is generated in the drive.
The most basic source of cogging torque is the interaction or attraction of the permanent magnets and the steel structure of the stator as the motor rotates. These attractions and overcoming them prevent the rotor from turning smoothly. Another source is the interaction of the rotor magnets and the stator winding when it is energized, due to harmonics. Cogging is often an undesirable feature, causing noise, vibration and non-uniform rotation, so during product development, minimizing this effect was a design “CTQ” (Critical To Quality). As a result, DEC Star® motors have extremely low cogging torque, resulting in smoother operation at all speeds, virtually eliminating torque and speed “ripple”.

The Evergreen IM is designed to replace 1075 RPM, direct drive PSC (Permanent Split Capacitor) indoor blower motors in any residential or light commercial HVAC system, 5 ton or less of cooling and 150k Btu or less of heating capacity. That includes all fossil fuels, electric heat, A/C, heat pump, dual fuel and geothermal systems. The Evergreen IM is built in two multi-horsepower sizes to replace 1/5 – 1 horsepower PSC motors. Both models are dual voltage (115/230) and dual rotation (CW/CCW). This reduces motor selection and inventory to just two for almost all applications.

  • 1/2Hp, CW/CCW, 115/230 (multi-horse power 1/5-1/2) part # 6005
  • 1Hp, CW/CCW, 115/230 (multi-horse power 1/2-1) part # 6010
In the broadest sense, the major difference is in the rotor itself. In a squirrel cage induction motor, current is induced into the rotor from the field (stator) through the air gap, and conducted through aluminum (or other material) bars, which are most often die cast in the slots of the rotor laminations. In the case of a DEC Star® motor, the rotor itself contains permanent magnet material, which is either surface-mounted to the rotor lamination stack or embedded within the rotor laminations. In either topology, electrical power is supplied through the stator windings.
It doesn't have to, but we chose this topology to reduce cogging torque.
Form factor is a different way of looking at power density. In this context, form factor refers to the physical (primarily dimensional) properties of the motor, which may be defined as the active materials or the overall envelope size. The simplest view of this is the frame size reduction potential of the DEC Star® versus IM…assuming the same power rating. Another way of looking at this is the ability to “down-frame ” the same power rating into a physically smaller package (frame size).
 

Double check your test setup for inefficiencies. You can also size up the blower/motor.

Yes. ECM motors must be programmed to be used. Programming instructions are only accessible by those who have signed an NDA.

Disconnect power to the unit and disconnect the capacitor from the capacitor leads. Measure the voltage across the capacitor. If there is not voltage then measure the capacitance. Measure the capacitance; if it is not within +/-6% of the rated capacitance it should be replaced. If the capacitor is good there are electrical issues (motor shorted, opened or grounded) and mechanical issues, (worn out bearings, broken lugs, rusted shafts) that may cause the motor to be inoperative but few if any of these are field repairable.

Constant Speed is used in applications where the static pressure is not changing. Examples include an outdoor condenser unit or a pedestal fan. Constant torque is used in applications where static pressure is expected to change. Examples would include any ducted system like residential furnace or air handler and commercial VAV units. The Constant torque option is easier than constant airflow for the OEM to test in applications and subsequently create Motor Application Programs for the motor.

12 months from installation, 18 months from manufacture.

Genteq offers the following ECM products: 142R, 3.0, Endura Pro, EON, EON 42, Ensite, Ensite Air, Glacair and Pika

Regal can test airflow at the blower and unit level in wind tunnels. Regal can also test sound power at the unit level in our two sound chambers (a fully anechoic chamber in Fort Wayne and a semi-anechoic chamber in Tipp City).

There are three standard locations for controller mounting avaliable: Motor Mounted (Radial Only), Side Panel Mounted, and Scroll Mounted.
