Inquiry (采购产品): DC Motors Hello, My name is Tom Chaney and I work for TriMet (Tri County Metropolitan Transportation District of Oregon), the regions largest public transportation agency in Portland, Oregon. We run both busses and light rail vehicles in our operation, and employ approximately 2,500 workers. I am writing to inquire about DC brushless motors. We are looking to replace our current motors (brush and comm) with a 'drop in' brushless motor replacement. We are looking for companies interested in manufacturing and/or supplying us with a brushless DC motor to be used in our hydraulic brake system to drive our hydraulic oil gear pump. I would like to know if your organization would like to be included in the bidding process for approximately 180 units. I am providing the basic overview of this motor in this email for you to determine if your company has the ability and desire to offer such a product. The formal documents and drawings will be included in the formal bidding offering in the future. Basic Specifications: 36 vdc ~4400 rpm ~550 watts Max housing length - 220 mm Max housing diameter - 110 mm Drive shaft diameter - 7mm Drive shaft length - ~17mm This motor is not a continuous use motor. It is turned on/off to maintain a hydraulic pressure supply in an accumulator. Please fel free to contact me for further clarification, as needed.
