Hi,
It seems that most washer and dryer motors run at about 1/3hp.
You do not say the size of your cabber, a large one will need more
than 1/3hp.
The following is just an example of what can happen when using the
wrong motor for the job in hand... 1/3hp versus 1/8hp
Given that most 10lb tumblers will happily run using a 1/8hp motor.
Given also that one uses 2.5 times more electricity than the other,
I only use the appropriate size new motors.
You will find that they more than pay for them selves in about 12 months.
Just a thought,
Derek
Good point Derek. I try to size the motors on a tumbler carefully. Because they run so much.
I have a homebuilt tumbler that started with a 16 pound barrel using a 1/8HP 1000 RPM roof top A/C motor.
I snuck a 35 pound barrel on it and it turns it too.
I know that I am saving electricity w/the 1/8 vs 1/3 by almost 3 to 1, as you mentioned.
Roof top A/C's here in the south see extreme temps. When fan is not running it gets very hot due to sun light.
It has to start hot, and always blows hot air. I think they are fine with a shaded tumbler.
And they are open cage motors as opposed to an enclosed motor.
TEFC = totally enclosed fan cooled, meaning motor has an internal fan.
Many totally enclosed motors have little to no fan.
Many AC motors have Nema designations on them. Here are most of them:
Drip-Proof
Ventilation openings in shield and/or frame prevents drops of liquid from falling into motor within up to 15 degree angle from vertical.
Designed for reasonably dry, clean, and well ventilated (usually indoors) areas. Outdoors installation require the motor to be protected with a cover that does not restrict the flow of air to the motor.
Totally Enclosed Air Over (TEAO)
Dust-tight fan and blower motors for shaft mounted fans or belt driven fans. The motors mounted within the airflow of the fan.
Totally Enclosed Non-Ventilated (TENV)
No ventilation openings, enclosed to prevent free exchange of air (not airtight). No external cooling fan, relies on convection cooling.
Suitable where the motor is exposed to dirt or dampness. Not suited in very moist humid or hazardous (explosive) air.
Totally Enclosed Fan Cooled (TEFC)
Same as TENV with an external fan as an integral part of the motor. The fan provides cooling by blowing air on the outside of the motor.
Totally Enclosed, Hostile and Severe Environment
Designed for use in extreme conditions - moist and/or chemical environments. Not for hazardous locations.
Totally Enclosed Blower Cooled
Same as TEFC with external fan on a power supply independent of the inverter output. Full cooling even at lower motor speeds.
Explosion-Proof Motors
The motor ambient temperature shall not exceed +40oC. Motors are approved for the classes:
