摘要：
A motor with DC brake having a DC electromagnetic brake (10) arranged on the shaft (14) of the rotor (16) thereof, in which a partial shaft (14b) extending through and outward from the DC electromagnetic brake (10) is formed of a nonmagnetic metal material. A partial shaft (14a) extending through the rotor (16) is formed of a free cutting metal material, and partial shafts (14a) and (14b) are coaxially united to form the integral shaft (14) at a junction (18) by friction welding.
