Re: Blendtec smoother 13 repair.

The blender has an electric brushed motor, 316472-01, commutator needs to be clean, that's it, the rotor spinning at 28,000 rpm is kind of important.

Pic8 : I connect pen and drill together to spin the rotor, steelwood and cotton swab, for cleaning.

PS: one question is what kinda coating I need to put on commutator(WD40)?

How's about 500F brake fluid (DOT5.1)?

PS: Or.... DOT 5 is silicone fluid.

After I clean the commutator, It worked, the story finished? No this is just A begin.

This is A good example. How to use microcontroller to improve the performance of your project.

Your Blendtec Blender features the most advanced microprocessor
available. Nine (9) blending speeds and thirty (30) pre-programmed
blend cycles are stored within its memory. With the touch of a few
buttons, you determine your blender cycle configuration. Experiment
with your recipes and the programs to determine which cycles are best
suited for you.

Re: Blendtec smoother 13 repair.

Blendtec Smoother 13 uses Universal Motor.

A type of electric motor that can operate on AC or DC power. It is a commutated series-wound motor where the stator's field coils are connected in series with the rotor windings through a commutator. It is often referred to as an AC series motor.

The universal motor is very similar to a DC series motor in construction, but is modified slightly to allow the motor to operate properly on AC power. This type of electric motor can operate well on AC because the current in both the field coils and the armature (and the resultant magnetic fields) will alternate (reverse polarity) synchronously with the supply. Hence the resulting mechanical force will occur in a consistent direction of rotation, independent of the direction of applied voltage, but determined by the commutator and polarity of the field coils.

The motor on the Blendtec Total Blender Classic series blender is a whopping 3 peak horse power, 13 amp, 1560 watt beast. pic3: Voltage 120v current:13A P: 1560 watts (Motor resistance = 8.4 Ohm). The powerful motor can push the blades from as low as 4080 RPMs to 28,000 RPMs and can over-power and liquify any ingredient you put into the blender jar including skins, seeds, leafy greens, tree nuts, avocado pits, popcorn kernels, large beets, pineapple cores, and much more. The Blendtec blenders are considered the most powerful blenders you can buy! From http://thedailyvitamin.com/blendtec-total-blender/

Universal motors have high starting torque, can run at high speed, and are lightweight and compact. They are commonly used in portable power tools and equipment, as well as many household appliances.

A universal motor's armature typically has far more coils and plates than a DC motor, and hence fewer windings per coil. This reduces the inductance.

Disadvantages:
A negative aspect is the maintenance and short life problems caused by the commutator, as well as electromagnetic interference (EMI) issues due to any sparking. Because of the relatively high maintenance commutator brushes, universal motors are best-suited for devices such as food mixers and power tools which are used only intermittently, and often have high starting-torque demands.

Speed control:
Continuous speed control of a universal motor running on AC is easily obtained by use of a thyristor circuit, while multiple taps on the field coil provide (imprecise) stepped speed control. Household blenders that advertise many speeds frequently combine a field coil with several taps and a diode that can be inserted in series with the motor (causing the motor to run on half-wave rectified AC).

Applications:
Dremel, miniature universal motor grinders exceed 30,000 RPM. vacuum cleaners, and hair dryers, washing machines, Starters of combustion engines are usually universal motors. (wiki)

TH1: Q6040K7TP-ND: Thyristors - TRIACs,TRIAC Alternistor, 600V 40A TO-218

Phase Angle Control...........It is the simplest method to control the speed of a universal motor. Speed control is achieved by the varying the firing angle for the TRIAC. Phase angle control is very cost effective solution but not very efficient and prone to EMI.

The Phase Angle Control mechanism typically employed for speed control of the TRIAC. A phase shift of the TRIAC gate's pulses allows the effective voltage, seen by the motor to be varied and hence the speed of the motor. A Zero Crossing Detection circuit is used to establish a timing reference for delaying the firing of the gate pulses.

the commutator has brushes that wear, so they are much less often used for equipment that is in continuous use. In addition, partly because of the commutator, universal motors are typically very noisy, both acoustically and electromagnetically.

PS: The IGBTs will replace TRIACs in the future. Next Topic will be, How Microcontroller does with Blendtec Smoother 13.

PS: Voltage 120v current:13A P: 1560 watts (Motor resistance = 9.23 Ohm).

Re: Blendtec smoother 13 repair.

I also have a Blendtec ICB3 SpaceSaver unit that has "no power" but with no power I mean that there is no response at all from the machine when the on/off button is used and power is connected. I'm thinking my control board is faulty, it stopped working after the unit was dropped.

For troubleshooting I have taken the unit apart and circumvented the on/off switch and plugged the neutral and line directly into the control board. Did not resolve the issue. So the on/off switch is likely not the issue.

Can you guys confirm for me that the control board is able to power up without the motor unit attached? Should the display power on when nothing is attached to the control board?

Has anybody here been able to resolve a similar issue? likely a power issue that is not motor related. Does anybody know where to find the control board part?

Re: Blendtec smoother 13 repair.

Hi.
I have a Blendtec ICB3 smoother that still give these overload error.
changed the brushed and cleaned the commutator but still that error.
could it be the speed sensor that is broken?if so where to find this.

[capwizard]

Re: Blendtec smoother 13 repair.

I've cleaned commutator by hand, Blendtec ICB3 still has a recall after 3M 400 grit sandpaper with hand-drill cleaned commutator up, no more problem. The point is that the surface should be very smooth and it will not produce a lot of sparks.

[Alain2003]

Re: Blendtec smoother 13 repair.

I did the same but still nothing,cleaned commutator by hand with sandpaper P400,the carbon brush still produce a lot of sparking.
i think the rotor is shorted out.replacement?

Re: Blendtec smoother 13 repair.

look at the picture, I connected center axis of the juicer to a hand drill then I pressed it down sandpaper with a toothbrush. You must do this to completely clean the commutator, because hand clean it will leave Scratch marks,

[R_J]

Re: Blendtec smoother 13 repair.

When you clean the commutator the way you do, all the brass debre ends up shorting the commutator, you need to clean between the brass sections.
I use a fiberglass burnisher.

Hi,

After i Disassembled twice used new carbon brushed and used your methode,its now fully working again.
thanks for the help.

Re: Blendtec smoother 13 repair.

I have a commercial blender which is a Blender model ABC-3 (It is a used blender that was originally used in a Subway sandwich shop and is almost if not the same as the Blendtec smoother 13). It gives me an error message after I press any one of the six (1, 2, 3, 4, 5, & P) touchpads buttons.

When I first received the blender I had to press the touchpad buttons numbers 4, 1, & 3 in quick succession to program the blender for manual mode, so it would start up whenever any of the buttons were pressed.

After turning the unit on, if any one of these buttons are quickly pressed, the blade will spin-up and stop. But if a button is pressed for about at least a ½ second before releasing it, to let the blender know that the press was deliberate, the blade rpm will continue to increase by itself for about another ½ second, at which point power to the blades abruptly cuts and “Overload” appears on the screen. (I can't tell if it is stuck in "Overload" or goes into "Overload each time a button is pressed).

This is obviously not a low voltage or over heating problem. The same exact thing happens regardless of which button I press or whether the jar is attached or not. (The jar blade spins freely). So I’m wondering if the “Overload” error and accompanying spin-down could be the result of dirt and grime inside the motor.

Any ideas on what to look for when I take the blender apart would be appreciated.

Thanks.
