Ø 12mm precision disc magnet stepping motor
EMS are delighted to announce the latest miniature
stepper motor from ARSAPE a member of the Faulhaber
Group, and leader in high precision, micro-mechanical
stepper motors.
The new Ø12x17.2mm motor with 2.4mNm holding torque and
boost torque of 4.1mNm complements the existing Ø6-22mm
range of stepper motors but the design is such that new
levels of precision, torque, speed range and mechanical
rigidity are achieved.
The motor is available in two versions with the ADM1220
offering, like any stepper motor, a holding torque
without current. The ADM1220S however has no holding
toque without current and as a consequence offers higher
motion precision. The disc magnet rotor technology used
in this motor is a proprietary design ensuring the
uniformity of parts the magnetic circuit design needs to
achieve a high precision motor.
The ADM1220S motor offers 20 full-steps per revolution.
Due to its unmatched sinusoidal torque it is fully
micro-stepping compatible, resulting in a precise 160
steps per revolution. This feature gives the motor the
excellent ability to run precisely at very low speeds
resulting in a wide useable speed range from below 10rpm
to over 6000 rpm.
Over the entire speed range the motor provides a useable
output torque of over 1mNm. Boost capabilities help to
increase the torque to 4.1mNm during critical phases of
the motion. Mechanical stability is assured by a large
shaft diameter of 1.5mm and rear ball bearing as
standard. Strong magnetic axial forces ensure that axial
play on the shaft is eliminated resulting in very low
noise.
The new steppers are also available with lead-screws
M1.2 and M2 for precise linear motion, or alternatively
are compatible with Minimotor gearheads of Ø10 & 12mm.
This particular motor design offers a low cost
alternative to more complex motion control systems in
high precision motion applications.
