These motors provide extremely high power output and meet tough load requirements. A thoughtful basic design and long-lasting carbon brushes cut down on maintenance requirements. All motors aremanufactured by Concentric to ensure maximal system optimization, performance and quality. He2000 adaptor can also be equipped with flanges for AC-motor mounting. MAKE THE OPTIMAL CHOICE OF PUMP AND MOTOR On the followingpages, youwill find our range of DCmotors and pumps. Important parameters toconsider in choosing the correct unit are flow in l/min, pressure in bars, and duty cycle. In some cases, allowable amp consumption is a factor too, due to restricted battery capacity. Our curves permit easy comparison at a constant voltage measurement. How to read the curves: When pressure and f low are determined, the amperage can be read from the pump/motor curve. The amperage is then transferred to curve 2. The amperage corresponds to an S2 and an S3 value. These values represent two ways of calculating duty capability. S2 is thenumber ofminutes a unit can operate at a certain workload before reaching the maximum allowable temperature. After this, the unit must cool down until the motor temperature is less than 2°C from the ambient tem-perature before the same S2 value can be applied again. S3 is the maximum time in % per 10 minute period that a unit can work at a certain pressure/ workload. For example an S3 value of 30% = 3 min. for each 10 min. period, over and over again. Pump motor (Instruction 12 MG32 Ø 80 mm) Example: 3,3 l/min at 90 bar and 80 amp on pump motor curve above gives S2 = 2,8 min and S3 = 11% at corresponding motor curve below.
