OUR CAPABILITIES Within the constraints of power input and motor size, Lin Engineering can design a motor to maximize torque at your desired operating speed. With a given power input, the power output ƒTd ω ( T = torque at angular velocity ω ) from a given size of motor will not change. In other words, we design a motor’s maximum operating efficiency at your desired speed. See page 9 for more information. Maximize Torque at Desired Speed Lin Engineering’s 0.45° NEMA 23 motor has the best step accuracy in the step motor industry. Our 0.45° motor is constructed with 200 rotor teeth (a typical 1.8°...

MAXIMIZING TORQUE AT DESIRED SPEED One of the most common issues with selecting the correct motor is getting the right amount of torque. That's how Lin Engineering's ability to Maximize Torque @ Speed can be utilized. Lin Engineering specializes in maximizing torque at your desired speed. Each step motor is characterized by its speed-torque curve, or, its power output capabilities. Within the constraints of power input and motor size, Lin Engineering can design a motor by manipulating the speed-torque curve to maximize torque in a given area across the speed range. In other words, we design a...

STEP MOTOR BASICS A Simple Tutorial for Common Stepper Terminology READING A SPEED & TORQUE CURVE The graph below depicts the relationship between speed and torque while a step motor is running. The output torque is very critical during the motor selection process. On the graph, the vertical y-axis represents torque (oz-in and N-m) while the horizontal x-axis represents the speed of the motor's torque (oz-in) Phase Connection Microstepping Current Scheme Setting represents the speed of the motor's shaft ROTATIONAL SPEED Step motors rotate continuously when given a specific series of pulses. Motor...

STEP MOTOR BASICS (Cont'd) The following table shows the number of pulses, or steps, for a given type of step When microstepping the motor, the number of pulses increases. This is because microstep- ping will cause the motor to step in finer, or smaller, increments. Instead of a 1.8° motor stepping every 1.8°, half stepping it will then force the motor to move every 0.9°. The motor then needs to step twice as much to go 1 full revolution, or a total of 400 steps. The following table provides the multiplier for each microstep: The amount of current going from the driver to the motor continuously...

BRUSHLESS DC (BLDC) BASICS how to read bldc curves The graph below provides three main motor specifications that can help users determine whether or not this BLDC motor is sufficient for the job. The left-side vertical Y-axis represents speed in revolutions per minute (RPM). The speed increments and the title “Speed (RPM)” are blue, which corresponds to the blue curve on the graph. The right-side vertical Y-axis represents Current in Amps. This axis is red, which corresponds to the red line on the graph. The horizontal X-axis is for torque in ounce-inches (oz-in). EXPLANATION OF AXIS ORIENTATION...
