Hybrid stepper motor

March 12, 2008

AMETEK Technical & Industrial Products introduced its MAE brand HN Series hybrid stepper motors, which 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 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 to 1076 oz-in can be achieved, depending on model.

All HN Series motors incorporate neodymium magnets for maximum torque and superior acceleration. They also have precision-honed stators and ground rotors for tight air gap and improved performance and single- or double-ended shaft extensions. Upon request, 4, 6, or 8 leads are available.

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.
