Stepper motors: Keep motion smooth and fine

Ametek says its new MAE brand “HN Series” hybrid stepper motors feature low detent-torque to holding-torque ratios, promoting smooth operation and fine positioning capability required for microstep operation.

Ametek saysperation suitable for a wide range of positioning applications. Standard Size 34 “HN Series” hybrid steppers are available in three models (lengths 2.64-in. to 4.92-in.) with step resolutions of 1.8º (200 steps per rev) in full-step mode. Holding torques (bipolar) from 397 oz-in. to1,076 oz-in. can be achieved, depending on model.
According to the company, all MAE “HN Series” motors incorporate neodymium magnets for maximum torque and superior acceleration; precision-honed stators and ground rotors for tight air gap and improved performance; 4, 6, or 8 leads upon request; single- or double-ended shaft extensions; and simple, rugged construction promoting high reliability and long service life.
Motor rotation can run clockwise or counterclockwise. Value-added customization options include gearboxes (planetary, spur, worm, or right angle) with standard or low backlash, encoders, brakes, and special shaft, endbelt, and cabling. They are CE approved, manufactured according to EN 60034-1: 1995-02 specifications, and can be provided to meet IP55 dust and splash-proof protection.
