Dynamically balanced armatures and non-contact ball bearings ensure a smooth performance. Durable totally enclosed, non-ventilated construction (TENV) and replaceable brushes help extend product life-cycles. And, for extra power and durability choose our DirectPower Plus motors. The ElectroCraft PMDC family is found in automotive, agriculture, medical, mobility, and other commercial markets.

Standard features incorporate ball bearings, high performance brush cards, zinc die cast endcaps, rugged black paint finish all with operating voltage ranging from 12 to 60 VDC. Additional mechanical configurations, shaft designs and winding options are available to customize a motor to meet specific customer requirements.

Our expert team of engineers is here to help you choose the PMDC solution that works best for your project. Contact us today and let us help power your innovation.

DirectPower™ Plus Brush Motors

ElectroCraft DirectPower Plus are high-efficiency servo motors.

PMDC Brush Motors

Hansen PMDC brush motors from ElectroCraft are useful for a variety of industrial applications, providing continuous operation over a speed range of 8:1 while delivering smooth control down to zero speed.
  • Series 116-1 1.6in DC Motor

    Series 116-1: 1.6 inch PMDC Brush Motor

    A 1.6" diameter permanent magnet DC brush motor with standard catalog stall torque ratings are in the range of 19 to 78 oz-in, while no-load speeds range from 1,700 to 8,000 rpm maximum. Encoders with line counts up to 2048 are available to provide velocity and position feedback information. Reliability is further enhanced by long life, pre-loaded ball bearings.

PMDC Spur Gear Motors

ElectroCraft offers a 2" diameter spur gearbox that is compatible with our 1.4", 1.6" and 2.1" diameter DC brush motors. These gearmotor packages are offered in a wide range of operating voltages and 4 gear ratio options, 12:1, 48:1, 192:1 and 768:1. Optional features include encoders, noise suppressors, custom shafts, custom leads and terminations, custom mounting and rear shaft extensions.

PMDC Planetary Gear Motors

ElectroCraft Series 116 and 121 gearmotors match our 1.6" and 2.1" diameter DC brush motors with either metal or plastic/polymer planetary gearing. This is an ideal gearmotor for medical applications where strong, coordinated, accurate motion control is required. The planet gears share the load attached to the output shaft giving the planetary arrangement a higher torque to volume ratio with low backlash compared to a spur gear arrangement. Gear ratios up to 642:1 are available. Encoders can also be added.
