SPEED CHANGERS & REDUCERS SCD/SYD Models Items Checked for Design Purposes 1. Temperature rise: Motors of up to 750 W have Class B insulation a n d m o t o r s o f 1.5 k W o r m o r e h a v e C l a s s F i n s u l a t i o n . Accordingly, the temperature rise limit of the armature winding is 90℃ and 110℃ . If the load is appropriate, the temperature of the outer frame is usually about 15℃ to 25℃ lower than the temperature of the winding. Therefore, it is so hot that you cannot touch it for a long time. However, you may continue operation if the temperature does not exceed the above value. in...
