Product Description:

Pacific Scientific's 3N63-100-2 low inertia motor is a member of the Low Inertia PMDC Servomotors series. The motor has a low-inertia rotor, and medium torque constant winding makes it stand out. Applications necessitating precision control and consistent velocity are suitable.

The motor's rated current is 1.9 A(rms), and its rated voltage is 30 VDC. Its 1.59 Ohm thermal resistance makes it ideal for continuous use, since it dissipates heat efficiently. The motor's torque output per ampere is defined by its torque constant, which is 7.9 oz-in/A. Rapid acceleration and deceleration are supported by the rotor's inertia of 0.00061 oz-in-sec². An incremental encoder is built into the 3N63-100-2 low inertia motor, allowing for extremely quick positional feedback. The motor is shielded from dust and low-pressure water by an IP65 housing. It is possible to get a high torque density while still maintaining a small motor design when neodymium magnets are utilized. The class H insulation guarantees safe thermal functioning. Medium torque applications requiring fast response and low electrical time constants are the intended users of this winding. The encoder keeps a constant signal output even while it is functioning at fast speeds. This is done in order to make the system more responsive and reliable.

The operating temperature range for the 3N63-100-2 low inertia motor is 0 to 40 degrees Celsius. This motor can be installed up to a maximum height of 1000 meters above sea level. When silicone vapors are present near PMDC motors, brushes wear out quickly. To ensure that the PMDC motor is functioning properly, avoid using silicone vapors. The 3N63 low-inertia motor is equipped with characteristics that are designed to fulfill the needs of industrial automation.
