EBI Dry Kiln Duty Motor Maintenance Instructions

EBI Kiln Duty Motor Bearing Greasing

  1. Grease bearings after each 720 hours of use.
  2. Properly clean grease fittings before and after each greasing of bearings.
  3. While motor is running, apply necessary quantity of grease.
  4. Let motor run sufficiently for grease to spread in bearings until grease excess starts coming out of grease fittings.
  5. However, if no grease comes out of grease fittings, make sure that grease fittings are functioning properly.
  6. To avoid overheating, do not apply more grease than necessary in bearings. This would increase resistance of rotating parts, compression of lubricant and consequently cause an eventual loss of efficiency.
  7. Clean grease fittings before and after each bearing greasing.
  8. Use non washable and high temperature synthetic grease (Sinto EP2 Calcium Sulfonate). Contact EBI for a list of equivalent products.
  9. Use the following table to apply correct quantity of grease: a small kitchen scale is necessary to assess the adequate amount of grease.
6200 à 6207 0.177oz (5 grams)
6208 à 6210 0.353oz (10 grams)
6211 à 6215 0.530oz (15 grams)
6216 0.705oz (20 grams)
6304 et 6305 0.177oz (5 grams)
6306 à 6308 0.353oz (10 grams)
6309 et 6310 0.530oz (15 grams)
6311 et 6312 0.706oz (20 grams)

EBI Dry Kiln Motor Inspections Every 6 Months

  1. Winding resistance and insulation resistance to ground with a multimeter and a megger;
  2. Winding resistance in ohms between phases (T1 vs T2 , T1 vs T3, T2 vs T3) must be the same
  3. Insulation resistance in megohms at 500vdc or 1000vdc
  4. Ground for feeding cable
  5. Condition of bearings
  6. On the shaft, axial and radial mechanical movement must not be apparent
  7. Make sure fan is properly fixed to shaft
  8. Junction box must be very clean without water or dirt inside
