The TGB2013 brush motor delivers extremely high shaft output power from a very small package. The TGB 2013 brush motor features the company's ironlesscore. The motors measures 2 in. diameter by 3.87 in. long and weighs only 34 oz. It delivers 400 watts (0.5 HP) of continuous shaft power with a maximum efficiency of 86 percent. At 18-volts, the motor runs at 13,400 rpm producing 40 oz-in of torque while drawing 26 amps. The linearity between torque and current allows a very high peak torque of 240 oz-in. The low inductance architecture of the motor permits faster current reversal at the commutation point, which reduces brush arcing and drastically improves brush life expectancy.
