Product Description:
The PMB31B-10101-02 brushless servomotor is part of the PMB Brushless Servomotors. It is a rugged, cost-effective servomotor by Pacific Scientific, and it is designed for use in industrial automation applications where precision, dependability, and constant motion control are essential. It falls under the NEMA 34 frame size category and meets typical feedback and motor cabling criteria.
The PMB31B-10101-02 brushless servo motor has a continuous stall current of 2.7 ARMS and a continuous rated torque of 1.9 Nm, which ensures consistent torque output during operation. The peak torque is up to 4.7 Nm, and the current at peak torque is 6.0 A. The servo motor has a rated speed (WR) of 2,700 rpm and a maximum no-load speed (WNL) of 4,300 rpm. The winding is defined at 2.7 A, which matches the constant stall current. It features a Hall sensor, which offers precise rotor position feedback. The feedback cable gauge is insulated at 26 AWG, which improves signal integrity. The motor cable gauge is shielded 18 AWG, which ensures reliable power transmission. The shaft is circular, which makes it suitable for direct mechanical coupling. The connector type is characterized as flying leads with amp connectors for easy integration. The inductance (L) is measured at 19.6 mH, which is consistent with the motor's current and voltage ratings for balanced electrical properties.
The PMB31B-10101-02 servo motor has a rotor inertia of 0.14 ×10⁻³ kgm² , enabling acceleration with load changes. The servo motor belongs to the NEMA Size 34 category, which provides dimensional compatibility in prescribed installations. The motor is designed for motion systems that require precise speed and torque control. It is utilized in systems that require high dependability and long-term operation. The combination of electrical and mechanical qualities makes it appropriate for a wide range of controlled drive applications.
