Product Description:
The PMB31D-10116-01 is a brushless servo motor design produced by Pacific Scientific. This motor is a very durable and cost-efficient product that was released more than 20 years ago and has remained one of the most trusted products for industrial engineers looking for high power density and performance standards in production and processing systems. The housing design of this industrial motor is shaped to make installation straightforward and fast. The motor also belongs to size 34 as defined by the National Electrical Manufacturers Association (NEMA). The ability of this motor to produce a high torque output makes it one of the most popular products of the manufacturer. The housing design of this motor is only able to provide protection against large foreign objects with a diameter larger than 1 millimeter, it provides no protection against liquids and should always be used indoors.
The PMB31D-10116-01 is equipped with a total of 8 pole pairs, this feature is responsible for the ability of the motor to produce high torque levels of about 6.25 newton meters and still maintain a relatively low operation speed of 6000 revolutions per minute. As a permanent magnet device, the Neodymium-iron-boron magnet is used in this servo motor. These magnets are lightweight and contribute to the impressive low weight of the motor unit. The winding in this industrial motor unit has an average voltage constant of 26.4 volts per revolution; its torque constant is also estimated to be about 0.79 newton meters per ampere.
The PMB31D-10116-01 servo motor unit uses a round shaft that can be directly connected to pinions and belt pulleys for the smooth transmission of torque. The feedback unit of the motor is a digital encoder with a commutation of 4096 parts per revolution.
Frequently Asked Questions about PMB31D-10116-01:
Q: What type of magnet is in this motor?
A: The PMB31D-10116-01 uses the Neodymium-Iron-Boron magnet.
Q: How is the heat produced by the PMB31D-10116-01 dissipated?
A: The PMB31D-10116-01 dissipates excess heat through the natural process of convection and radiation from its housing.
