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. 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 Types / Mechanical Characteristics Overview: Extensions ' Stepper motor * Stepper motor with motor brake Permanent magnet brake for * Stepper motor with encoder ' Stepper motor with encoder * Stepper motor with low-backlash planetary gear Reduction ratios from 3:1 to 512:1 Technical Information • 2-phase hybrid stepper motors • Number of steps: 200 / step angle: 1,8° parallel windings, with terminal box • Holding torques from 0.45 to 17 Nm • Protection class: IP 54, optional: IP 68 • Permiss. operation temperature: -30 to +80 °C (up to 100 °Cfor short time) • High permissible axial and radial bearing loads • Free wire ends (IP 41) • Motor brake Low-backlash planetary gear customized solutions

Frequency Characteristics Frequency Characteristics The motor windings are connected in parallel (fig. 11), the motors are powered by bipolar stepper motor power stages in the half-step mode. The curves correspond to the limit values of the operational characteristics as a function of the control pulses (frequency/speed), for two different supply voltages (Ub).

Planetary Gear / Motor Brake / Encoder / CE / Ordering Code Optional: PLE Low-backlash Planetary Gear Optional: KEB Motor Brake The use of a gear box is recommended if a high resolution of the drive system or a low output speed is required. For vertically mounted positioning systems, stepper motors with brake are recommended. ZSH stepper motors with mounted encoder are specially adapted for applications with variable speed drives or to monitor the drive.
