Induction heaters for mounting Motor Bearings
In the maintenance of electric motors periodic inspection of Insulation levels, vibration levels temperature rise and motor noise are generally considered a good practice. When the noise or vibration levels increase significantly it is an indication that the bearing could need lubrication or a complete replacement. Bearings could be mounted using mechanical methods like pressing but this method poses a significant risk of damage to the bearings. This is why heat is used to expand the bearings so that it could easily slide into the shaft and grip the shaft firmly as it cools. The procedure for using a bearing heater is pretty simple and generic. The appropriate yoke close to the inner diameter of the bearing to be heated is selected. This is important for effective and even heating. Then the bearing is placed in the yoke or over the coil. After this, the required temperature is chosen and the heater is switched on then the temperature starts to rise. How induction heaters work
