Specifications subject to change without notice.Additional InformationBalancing All cylinder motors in this section have their rotors dynamically balanced on two planes through a material removal process.Hall sensors An external pull-up resistor is required on drive electronics.Power curveThe typical power curve shows the continuous operation working points possible (the colored part of the chart).This is based on purely thermal limitations (the same limitations described under “Max continuous current”) that change depending on the cooling conditions of the application – for example, when the motor is mounted to a metal part.These power curves are common to all coils presented, and they represent typical motor performance with the understanding that many parameters influencing the curves have tolerances around nominal values (no-load current, resistance, torque constant, etc.). These power curves are not plotted at nominal voltage; each working point illustrated will require matching of coil, voltage and load to reach the indicated speed.Dotted lines show the torque/speed relationships that deliver a given mechanical power value (in watts) at the motor shaft.Working points outside of the illustrated continuous operation range are possible depending on the duty cycle.In some cases, the power curve stops early on the high-speed side before the limitation is reached (the flat portion on top of the curve) because measurement was not possible at higher speeds.In some cases, the maximum recommended motor speed is lower than the maximum continuous thermal limit shown on the power curve. This recommendation is based on characteristics of the bearing assembly.Dielectric test A dielectric test (also known as hipot or high potential test) is performed on all motors under 500V phases to the housing and during 5 seconds after voltage ramp up. Maximum allowed leakage is 1mA.15
