The new MAE brand "HN Series" hybrid stepper motors from AMETEK Technical Industrial Products feature low detent torque to holding torque ratios promoting smooth operation and the fine positioning capability required for microstep operation. These motors can provide accurate open-loop control and high-speed operation suitable for a wide range of positioning applications, the company says.

Standard Size 34 "HN Series" hybrid steppers are available in three models (lengths 2.64" to 4.92") with step resolutions of 1.8º (200 steps per rev) in full-step mode. Holding torques (bipolar) from 397 oz-in to 1076 oz-in can be achieved, depending on model.

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. The motors are CE approved, manufactured according to EN 60034-1: 1995-02 specifications, and can be provided to meet IP55 dust and splash-proof protection.
