Product Description:

The PMB33C-00101-03 from the PMB Brushless Servo Motor series is manufactured by Pacific Scientific. It has an IP40 ingress protection rating for moderate environmental resistance. The motor is designed to work on tasks that need proper response and constant duty in industrial devices and automated systems.

The PMB33C-00101-03 brushless servo motor is fitted with a rated speed capacity of 1300 revolutions per minute that provides continuity of rotational output. Its steady state current is kept around 3.8 amperes to enable long term constant operation. The motor comes with Hall effect sensors that provide dependability in closed loop control operations. Its shaft also has a sealing system coupled with a thermal sensing element to make itself durable and to check the heat. The servo motor frame dimension is NEMA 34 compatible which allows versatility with the usual mounting systems. It has a maximum intended torque of 11.4 newton meters capable of supporting a high load response. The PMB33C-00101-03 brushless servo motor electric interface has flying leads with AMP connector terminations to ease wiring. It can work in a quite wide range of -20°C degrees to +60 °C. The servo motors fast acceleration and stop start reaction are enabled by a rotor inertia of 0.00040 kilogram meter squared. Its miniature dimension of the motor body is 210.3 millimeters to fix in a compact installation space.

The PMB33C-00101-03 brushless servo motor offer effective torque and rotational control and are reliable throughout the industrial automation equipment. Its winding inductance is 27.2 millihenries that facilitate smooth dynamic performance. The servo motor has a flat shaft system, which is part of a shaft seal and a built in PTC thermistor which offers thermal protection.
