Why is this important? FAQ
- Why is Class H insulation important? Type H insulation class means that the insulating materials, as well as the varnish, are designed to withstand up to 180oC (356oF). This is absolutely essential in a high temperature application such as in a wood kiln. Not only does it must succeed in withstanding the high temperature of the air circulating in the dryer, but also the heating of the motor when it is operating at full load can have a temperature rise of up to 60oC (141oF) sometimes.
- Why are oversized bearings used? The ball bearings on the opposite side of the shaft are large enough to withstand the back-and-forth motion and crankshaft effect caused by the dry kiln fan. By also having bearing retainers, which help hold the bearings in place, gives the bearings greater endurance.
- Why is TEAO an advantage over TEFC? The TEAO envelope is above all more advantageous than that which can be found in the dry kiln motor market, i.e. ODP (Open Drip Proof). The TEFC casing can perhaps be an alternative, but its defect lies in the fact that having a fan at the rear of the motor, there will always be a risk of infiltration and congestion of wood dust on this side. The ODP envelop was often used by some dry kiln manufacturers in the past because at that time it was the only solution that existed to be able to ventilate the inside of the motor and allow it to – some extent – last a little longer than a standard motor class F. The disadvantage of having ODP is that moisture, dust and all corrosive elements and eventually destroy the insulation of the motor winding and the service life is not more than 2 years on average
- What is your topicalization process? This is EBI’s secret of their recipe, but EBI does their utmost to protect the motors against heat, humidity and corrosion. Using the lap winding method for the design and installation of the coils of copper wire in the stator allows much better use of the stator steel and more even heat dispersion, thus increasing its life. However, this method requires it to be done by hand instead of using robotic equipment.
- What is your warranty process? EBI suggests that the customer first have their motor inspected at an EASA member motorshop to make sure the job is done properly. Subsequently, according to the report received from the motorshop, EBI is able to make an informed decision. If it is a warranty case, the customer will have the choice of taking a new motor or a credit for a future purchase.
