Mclennan continues to expand its range of stepper motors from USA distribution partner Applied Motion Products (AMP) with new smaller sized high-torque stepper motors in NEMA frame sizes 8, 11 and 14 as well as a range of 400 full step per rev motors.
The new miniature stepper motors will suit motion automation applications such as medical and laboratory equipment, camera controls, pumps and consumer electronics where installed space is limited but high torque and precision positioning is essential.
The 0.9 degree stepper motors, featuring 400 full-steps or 800 half-steps per rev with normal stepper drives, will provide smoother and quieter performance than the standard 1.8 degree motors in applications where microstepping drives are considered too elaborate, not available or where a basic half step drive is already specified.
The new compact NEMA motors are all 2-phase, 4-lead bipolar connected and range from size 8 - about 20 mm square - to size 14 which is around 35 mm square. Through the range the motor length is from around 26 to 53 mm with available holding torque from 1.5 to 18 Ncm. The 0.9 degree motors are offered in NEMA frame sizes 14, 17 and 23.
