The downhole motor includes a power section operatively coupled with a bearing section. A drill bit is operatively connected with the bearing section. The power section has a power section housing, and the bearing section has a bearing section housing connected with the power section housing. The bearing section housing is a unitary piece having a first bend at a first bend angle. In operation the downhole motor provides three known or controlled contact points in the wellbore. ## Claims ### Claim 1 A downhole motor for use with a drillstring in drilling a wellbore, the downhole motor comprising: a power section configured to operatively connect with the drillstring, the power section comprising: a power section housing;
