(3) Improved motor performance
The Models WH 12DH and WR 12DH are compact and have high power thanks to the rare-earth magnet
motor. Furthermore, these models have better heat resistance because the built-in fan enhances cooling
efficiency. Their motors have replaceable carbon brushes, and the service life of the carbon brush has been
extended by increasing its volume (by about 30 % compared to our previous model) and making seven slots in
a motor armature core.
