Product Description:
The Pacific Scientific 2VM61-020-2 is a low-inertia permanent magnet DC (PMDC) servomotor that is designed to be responsive in terms of position.
This motor is of the 2VM series, which is characterized by its compact design, low rotor inertia, as well as excellent control characteristics. Having a continuous current rating range of 3.1 to 5.7 amps, operating at 18 to 36 volts, it will deliver reliable performance in low-voltage applications and is an excellent choice in robotics, light automation, or mobile platforms. The motor has a rated torque of 16 oz-in or 0.113 Nm with a maximum pulse current of 28 amps or the ability to achieve short bursts of power when heavy work is required. It has a low inertia design as its no-load speed at full voltage is up to 6010 RPM. The motor is now responsive to applied current, allowing for the establishment of the necessary torque levels, as indicated by the torque constant of 0.041Nm/A.
At 25 °C, the motor's electrical time constant is a low 0.17 milliseconds. Fast dynamic responsiveness is also provided by its conjunction with a mechanical time constant of 3.6 milliseconds. In Motor, the resistance of the motor terminals depends on temperature: 3.0 ohms at 25 °C and 4.41 ohms at 155 °C. Thermal resistance is 2.13 °C/W, with continuous capability of dissipating 54 watts of heat- making it appropriate to handle constant duty operations with adequate heat sinking. Low rotor inertia of 3.3 x 10⁻⁶ kg·m² allows quick acceleration and deceleration of the 2VM61-020-2. It is weighted at 2.75 lbs (1.25 kg) and is fit to be used in dynamic motion. It can be purchased at Wake Industrial with a one-year warranty.
