Product Description:

Pacific Scientific manufactures the PMB33C-10101-01 brushless servo motor. The 6.3-kilogram motor is engineered for incorporation into systems that demand efficient driving performance. Compact, precise, and consistently delivering torque are the hallmarks of its intended use in motion control applications.

The torque constant of 1.85 Nm/A is consistent with the voltage constant of 1.17 V/krpm of the PMB33C-10101-01 brushless servo motor. The motor generates a maximal torque of 15.9 Nm at a current of 8.6 A. The inductance is 23.4 mH, and the resistance between the lines is 8.4 ohms. The motor maintains a typical rated speed of 1,350 rpm and operates at a typical rated torque of 4.9 Nm. The maximal value of static friction is 0.169 Nm. A constant 2.9 A stall current is the same as 5.3 Nm of continuous stall torque. The viscous damping coefficient, which is 0.038 Nm/krpm, defines the speed-dependent torque behavior of the motor. The motor is designed for closed-loop control applications that necessitate consistent performance under varying loads. The thermal resistance of 0.78 °C/W enables the efficient management of thermal energy during continuous operation. Under temperature controls set according to its rated specifications, the motor keeps its torque output constant.

It takes 32 minutes for the motor to reach thermal balance, which controls how quickly it does so while it is running. The speed at which the <
