Product Description
The PMB31B-00114-01 is a brushless servomotor from Pacific Scientific. The manufacturer is well-known for the different types of motors that it produces to meet several requirements. The motor features an IP40 construction style. It operates at a maximum bus voltage of 240VAC or 320VDC.
The brushless servomotor is compatible with PC3403, PC8x2, SC9x2 and SCE9x2 servo drive models. The unit has a 2.7A winding and a frame size of NEMA 34 mount. It also encompasses a digital encoder with commutation, a flat shaft, flying leads and a 2048ppr sensor. The motor features an AMP mini Mate-N-Lock type connectivity option on 18” lead connectors. The B series motor has a peak rated torque of 6.26Nm, a rated speed of 2,900 rpm, a B winding designator and a line-to-line inductance of 19.6mH. The device offers a customization option for a shaft seal. The unit operates at an ambient temperature of 25°C. It features a thermal time constant of 28 minutes, a thermal resistance of 1.08°C/Watt and a viscose damping coefficient of 0.0124Nm/kRPM.
The motor has a lightweight and compact size with an overall length of 5.28 inches and a weight of 2.5kg. The 8-pole unit houses magnets made of a combination of neodymium, iron and boron to produce maximum torque for better efficiency. The device comes with multiple stack length and must be mounted using four socket-lead or fillister-lead cap screws and #10 size screws. The motor has very low inertia both with the resolver and with the encoder. The double shield for the bearings ensures less wear and tear while the motor by itself features Class F winding insulation with an exposed-lam design. It is used to meet requirements that demand high torque and speed. The brushless black colored cost-effective device is a good choice for high volume and light industrial applications.
