Nov , torque and speed go hand in hand when selecting a servo motor torque curves are a tool used to represent this relationship, showing when relative torque and speed can be sustained simultaneously, both continuously or intermittently two other useful terms to know about torque in servo motors and the torque curve are rated torque and rated speed
Calculation for the effective load torque trms for servo motors and bx series brushless motors when the required torque for the motor varies over time, determine if the motor can be used by calculating the effective load torque the effective load torque becomes particularly important for operating patterns such as fastcycle operations
A step motor is a constant output power transducer, where power is defined as torque multiplied by speed this means motor torque is the inverse of motor speed to help understand why a step motors power is independent of speed, we need to construct figuratively an ideal step motor
Jun , the acceleration phase of the move profile is typically the period when maximum torque is required from the motor, and this torque value, t a, is often taken as the intermittent torque the torque required during acceleration includes the torque required at constant speed plus the torque required to accelerate the load
More stringent specifications regarding motor vibration call for maximum velocity levels of inSec on the housing and mils of displacement vibration on the shaft the limits apply to a motor mounted on a seismic mass, and uncoupled or coupled to a piece of equipment in a way that eliminates any vibration in the driven equipment
Torque equation of an induction motor the developed torque or induced torque equation in a machine is defined as the torque generated by the electric to mechanical power conversion the torque is also known as electromagnetic torque this developed torque in the motor differs from the actual torque available at the terminals of the motor, which is almost equal to the friction and windage
