- 2. NOTE: Continuous torque specifications obtained with motor mounted to an 8.5”x12”x 0.25” aluminum plate at 25°C ambient. Typical values are within ±10% of rating. Relationship Between Ke & KT Torque Systems uses the following important motor performance 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 current driven amplifiers *Krpm = 1000 rpm For “RMS” values, divide peak values by √2 STANDARD SPEED/TORQUE CURVE DATA FOR SIZING A SERVO MOTOR Nm = Maximum speed, continuous operation Tcs = Continuous stall torque All specifications subject to change without notice.

Standard BNR3300 motor mounting flanges use NEMA 34 standards but have oversized shaft diameters to carry the rated torque load. Standard NEMA shaft diameters are typically undersized for most servo ratings and are not recommended. Consult CMC regarding acceptable load limits before ordering or applying this option. 2. The above motors include standard MS connectors. Connector mates or cables must be ordered separately. 3. Standard encoders are dual channel line driver output with a marker pulse and complementary outputs. 4. Brakes are for holding static loads and not designed to stop moving loads.
