Product Description:

The Pacific Scientific manufactured PMB Brushless Servomotor under the PMB33C-10101-03 model number. It appears in precision controlled motion systems. It provides uniform torque and faultless work throughout industrial tools. The main actuator provides uncompromising torque stall of 5.42 Newton meters that ensures reliable motion under standstill.

The PMB33C-10101-03 servomotor includes a maximum torque of 11.40 Newton meters to deal with abidance. It has a thermal resistance of 0.78 degrees Celsius per Watt which facilitates adequate heat dissipation. The motor has flying lead electrical connectors AMP style terminals to facilitate easy installation. The rotor position feedback is made accurate by an integrated Hall effect sensor system. It also has a stator winding with a stable thermal operating value of 3.8 Amperes root mean square current. The PMB33C-10101-03 servomotor is rated at 6000 revolutions per minute of continuous load. The rotor has 8 magnetic poles to enhance torque response during high speed shifts. It has an ingress protection rating of IP40 allowing it to suit closed spaces with minimal dust contamination. The static friction torque is 0.169 Newton meters and it helps to obtain low startup mechanical resistance. It has a damping of the 0.038 Nm/kRPM so that it can decelerate very smoothly. The weight of the whole motor is 6.3 kilograms which makes the system stable under fixed applications.

The PMB33C-10101-03 servomotor phase resistance is marked as 8.6 ohms and phase to phase voltage is maintained stable in windings. It has a 27.2 millihenry phase inductance that facilitates smooth transitions with changes in loads. The rotor inertia is set to 0.404×10⁻³ kilogram meter squared and ideal speed control is attainable.
