Introduction

All KitchenAid Stand Mixers are well designed and carefully built. Normally they will give continual use year after year without service attention.

Careful records have been maintained over a period of years to determine and correct, through improved design, any troubles that might possibly develop.

An effort has been made in preparation of this manual to cover them all.

Heating

Under normal conditions, the mixer will not show any tendency to heat because of the built-in ventilating system in the motor.

Under heavy loads with extended mixing time periods, the head may heat up to the point of being uncomfortable to touch.

Speed Control

The speed control of the mixer is attained through the use of a governor assembly mounted at the rear of the control plate assembly.

The electrical circuit is made and broken by the action of the fly ball governor revolving against the control plate.

When the switch lever is moved to an ON position, the position of the control plate with respect to the governor is changed by the action of the switch lever.

Thus, when the control plate is set close to the governor, a relatively low speed of the motor causes the governor to make or break the mixer's electrical circuit through the control plate.

When the control plate is set farther away, a greater motor speed is required before the governor starts breaking the circuit.

The action of the governor is such that the speed of the motor will remain constant for a given setting of the control plate within certain loads.

After certain loads have been exceeded, the speed of the motor will drop to meet the torque requirements of the given load.

Speed is controlled by the governor and the control plate in conjunction with the phase control.

TRIAC RMS VOLTAGE

BOTH CONTACTS OPEN - 40 VOLTS ONE CONTACT OPEN - 80 VOLTS BOTH CONTACTS CLOSED - FULL VOLTAGE NOTE: The triac regulates the power the motor sees depending on control board contacts.

A device called a triac is a part of the phase control circuit.

This device determines the amount of power the motor sees dependent upon the condition of the control board contacts.

If both contacts are open, about 40 volts RMS is applied to the motor and about 80 volts is applied when either contact is closed and the other is open.

GENERAL INFORMATION Normal Performance

The KitchenAid Stand Mixer is powered with a universal motor which will operate on 50 or 60 hertz, alternating current only.

The Voltage of the power supply should be within 10 volts either way of the voltage stamped on the mixer trimband and nameplate.

A mixer in good running condition will start turning slowly when the switch lever is moved from the 'OFF' position to the 'STIR' position.

As the switch lever is moved to successively higher positions, the speed of the beater increases until the #10 speed is reached.

At stir position, the planetary should turn at
