Product Description:
The Pacific Scientific 55NM82-100-2 DC Motor is engineered for precision driven industrial applications that demand consistent torque and efficient performance. It operates at a rated voltage of 30 V DC and provides a stable electrical output for continuous duty cycles. Its dual shaft design supports various coupling options.
This 55NM82-100-2 DC motor delivers a rated current of 8.0 Amps RMS that ensures reliable power under operational loads. The terminal resistance of the motor is 0.50 Ohms that minimizes energy loss and improves efficiency during operation. It features a torque constant of 15.6 oz-in/Amp that offers consistent torque output per unit of current input. The rotor inertia is 0.085 oz-in-sec² for quick dynamic response and improved speed regulation. These specifications make the motor suitable for applications requiring precise control of acceleration and deceleration. The dual shaft includes a front splined shaft and a smooth rear shaft with a tapped center hole. This feature allows for load and feedback device coupling at either end. The face of both end bells includes multiple mounting holes that offers versatile installation options in equipment or machinery enclosures. This motor integrates easily into motion control systems, robotics, conveyors and custom industrial machinery.
The 55NM82-100-2 DC motor housing is designed to ensure structural integrity and environmental protection. It features a smooth cylindrical metal body with a blue enamel finish which serves as a non conductive surface coating to prevent electrical interference and corrosion. The machined aluminum end caps enhance durability and maintain precise alignment of internal components. The compact build and robust enclosure make it suitable for enclosed or semi exposed installations. These design elements support reduced maintenance and long term performance consistency.
