ZSH 57 to 107
2-Phase Hybrid Stepper Motor
ZSH Precision Stepper Motors
The highly dynamic ZSH 2-phase hybrid
stepper motors are constructed for operation in
industrial environment.
Holding torques: 0.45 to 17 Nm.
ZSH stepper motors are available in size 57,
87,88 or 107 mm in diameter. Each motor size
includes 3 or 4 motor types of the same
diameter but different length. Furthermore,
each motor type can be delivered with 2 or 3
different standard windings.
When installed and wired correctly, ZSH
stepper motors meet the requirements of the
EMC and Low Voltage Directives.
