Glossary (for Brushless Slotless DC Motors) Electrical Data Nominal voltage This voltage is used when measuring no-load speed, no-load current and other parameters. It does not represent a recommended voltage or a limitation of the motor. Brushless motors equipped with Hall sensors can be tuned so that the sensor positions compensate for the electrical and electronic time response of the commutation sequence. This is especially important for reducing motor losses in high-speed applications. Optimization direction All the standard motors shown in this catalog are either symmetrical or...

Back EMF is a voltage generated by the windings of a permanent magnet motor in rotation. Because this voltage increases with speed and is applied in the opposite direction from the input voltage, the back EMF constant can be used to calculate the motor’s speed at any given input voltage, assuming no friction and no loading torque. The specification document also gives the 0-peak value of the back EMF, which is typically higher than the average value and can be measured on motor phases with an oscilloscope while the motor is back-driven. Torque constant This value relates the current in the...

Glossary (for Brushless Slotless DC Motors) General Data Maximum motor speed This is the maximum recommended speed as limited by the bearing assembly type, taking into account the bearing supplier’s specification, vibration behavior and other factors. Ambient working temperature range The recommended ambient working temperature range is based on the properties of the bearing lubricant. Ambient storage temperature range The recommended ambient storage temperature range is based on the properties of the bearing lubricant. Ball bearings preload This is the bearing preload force as implemented...

Additional Information Balancing 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. The 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. Power curve These...
