Baldor FLEXIDYNE 11C - Manual (Page 7)

FLEXIDYNE Trouble Analysis
Symptom Cause Cure
Vibration 1. Misalignment 1. Realign drive or coupling.
2. Bent shaft 2. Replace or straighten.
3. Excess flow charge 3. Remove small amount of flow charge.
4. Fused flow charge 4. Correct the overload.
5. Improper installation – Output shaft jammed
against housing
5. Readjust spacing between shafts and
FLEXIDYNE.
Erratic Acceleration 1. Breakdown of flow charge 1. Replace flow charge.
2. Caked flow charge 2. Moist environment – use stainless flow
charge.
FLEXIDYNE Doesn’t Slip 1. Improper installation – Output shaft jammed
against housing
1. Readjust spacing between shafts and
FLEXIDYNE.
2. Flow charge in bearings – causing bearing
seizure
2. Replace seals, bearings and flow charge
or replace FLEXIDYNE.
Excessive Slippage 1. Not enough flow charge 1. Add flow charge.
2. Overload 2. Relieve overload.
3. Worn flow charge 3. Replace flow charge.
4. Worn rotor 4. Replace rotor.
Poor or short flow charge life 1. Excessive slip at start up 1. Add flow charge to reduce starting time.
2. Excessive inching or jogging of machine 2. Install time delay in motor control circuit.
FLEXIDYNE Flow Charge Analysis
Condition Cause
1. Red oxide color, granular consistency 1. Normal after some usage.
2. Red oxide color, powdery consistency, possibly with
powdery flakes
2. Worn-out, can cause FLEXIDYNE
damage.
3. Black, powdery 3. Rotor worn, excessive slip and heat.
4. Red oxide, powdery and chunky 4. Worn-out and moisture present.
5. Clumping of flow charge 5. Moisture present, use stainless flow
charge.
