9 Volt - Maxon F 2140 (ball bearing model) The sale is now for a lot of 2 motors.These motors were purchased for a project that changed before they were ever mounted or used. They are brand new motors in the original packaging. They originally came equipped with a disk with two magnets. The disks were carefully removed from the motors by pressing the shaft of the motor out away from the disk, so that the bearings would not be exposed to the pressure of removal.  No load speed at 9 volts - 4630 RPMNominal speed at 4 Watts - 2990 RPMMaximum efficiency - 82%Stall torque - 39.5 mNm See the photo of the Maxon catalog page provided here for the specifications of this (932 winding) motor. The model number of this motor is 2140.932-22.112-008. This particular model motor comes with precious metal brushes and ball bearings. They also came with a special disk with magnets. The last three digits of the model number (050 or 008) probably refer to accessory options, stock (050) or in this case custom fitted (008). Since the disks have been removed, none of these motors have the special disk. They are nice motors. Wish we could use them.  
No defects. Package has been opened. Never electrified.
