Product Description:
Pacific Scientific manufactures advanced automation equipment made for effective and efficient performance in industrial automation systems. The PMB33C-20100-01 Servomotor is made to provides efficiency in motion control applications. It provides accurate synchronization under variable operating conditions. The motor delivers stable automation functions with consistent energy conversion.
The PMB33C-20100-01 servomotor has an 8-pole synchronous design. The pole configuration offers accurate angular positioning and stable operation in servo control systems. The continuous stall torque rating is 5.42 Nm. This torque capacity supports sustained loads without loss of rotational accuracy. The maximum torque value reaches upto 16.1 Nm. The available torque margin accommodates short-term load surges in demanding cycles. The rotor inertia is 0.404 kgm² x10⁻³. The low inertia value allows rapid acceleration and deceleration for dynamic response. The maximum static friction is 0.169 Nm. The low resistance to motion minimizes startup torque losses and provides smooth shaft rotation. The viscous damping coefficient measures 0.038 Nm/kRPM. The damping characteristic stabilizes shaft velocity under continuous load variations.
The PMB33C-20100-01 servomotor has a thermal resistance of 0.78 °C/Watt. The thermal parameter governs heat transfer efficiency during continuous power dissipation. The thermal time constant is 32 minutes. The extended time constant indicates gradual heating, which allows stable operation over long duty cycles. The motor weight is 6.3 kg which makes the integration easy with other industrial systems. The brushless servomotor has structural balance for low vibration. The physical design supports reduced wear on connected bearings and couplings. Wake Industrial offers a one-year warranty on this brushless servomotor in addition to shipping services worldwide. The Pacific Scientific servomotor is specified to meet challenging automation needs with controlled thermal and mechanical performance.
