BRUSHLES S SERVO MOTORS BNR 3300 SERIES
Series 3300, 325 VDC brushless servo motor — provides fast response, accurate control and high torque-toinertia ratios
Performance Benefits
Cleveland Motion Controls specializes in the design of high performance brushless servo motors that provide efficiency, flexibility of application, and a long and trouble-free servicelife. Our BNR 3300 series is no exception. With fast response, accurate control and high torque-to-inertia ratios, you can count on the 3300 series of servo motors to provide smooth operation throughout a full speed range. The BNR 3300 Series delivers smooth and superior low speed performance, and maximum power ratings with low thermal resistance for high speed performance. In addition, with maximumtorque in a smaller package, you can count on better pricing for a better overall value. When integrated with high performance brushless amplifiers, BNR 3300 servo motors provide effective and highly efficient motion control solutions for a wide range of applications—including factory automation, packaging, robotics, machine tools, semi-conductor, medical instrumentation, and more.

DesignFeatures
BNR 3300 Series servo motors are rated from 12 lb-in. to 34 lb-in. with speeds and torque stability up to 10,000 RPM — accommodating DC bus voltages up to 325 volts. They utilize the latest in high performance Neodymium permanent magnet technology, and are available in several standard windings to meet your most demanding applications. Each servo motor in the 3300 Series is ruggedly designedand manufactured for reliable performance. To satisfy many different applications, 3300 Series motors are manufactured to NEMA/IEC specifications. For severe duty environments, the BNR design is also available with IP65 sealing.

NOTE: Continuous torque specifications obtained with motor mounted to an 8.5”x12”x 0.50” steel plate at 25°C ambient. Typical values are within ±10% of rating. Relationship Between Ke & KT Cleveland Motion Controls uses the following important motorperformance parameters for the 3 phase square wave and 3 phase sine wave brushless motors in order to properly account for the British Imperial unit system currently used in the US. Ke = Line-to-line volts-peak / Krpm* KT = Pound-inches (lb-in) / peak phase amps Ke is related to Kt as follows: KT = Ke/11.834 for 3 phase square wave current driven amplifiers KT = Ke/13.662 for 3 phase sinusoidal wave...
