Product Description:

The PMB31B-10214-00 Brushless Servo Motor has the highest level of torque and precision. It is also designed with an 8 pole synchronous structure that makes it smoothly operative and ensures that it conveys an optimal output of torque. It suits any application that needs a robust motor with reliable performance in harsh environments and with a compact NEMA 34 frame size.

The PMB31B-10214-00 brushless servo motor from Pacific Scientific is engineered with advanced neodymium iron boron (NdFeB) permanent magnets which provide a high flux density. These high performance magnets enhance the motor's efficiency and power to weight ratio. They allows for greater torque production while maintaining compactness and reduced weight. It offers superior performance in industrial applications with a peak torque of 2.11 Nm and a typical rated torque of 1.90 Nm. The motor operates efficiently within a wide voltage range with a maximum operation of 240 V AC and 320 V DC. Its thermal time constant of 28 minutes allows for efficient heat dissipation. The motor features a continuous stall current of 2.66 A that ensures stable operation under varying loads. A digital encoder with 2048 pulses per revolution (PPR) is included in this motor. This enables precise commutation for accurate position feedback. The round shaft design of the motor allows for easy integration into various machinery setups.

The resistance of the PMB31B-10214-00 brushless servo motor is 7.6 Ohms that provides effective current distribution. It has a viscous damping of 0.0124Nm/kRPM that provides smooth performance. Its motor inertia of 0.137 10-3 kg-m2 is capable of achieving fast response times and minimal mechanical delay. The IP40 construction of the motor gives it sufficient protection against dust and debris. These specifications render this motor to be useful in applications that need precision high torque and reliability over a long period.
