Product Description:

103-770-3251 stepping motor is a device designed for precise motion control in industrial applications. It supports operating frequencies of 50 Hz and 60 Hz, making it adaptable to different power systems. This motor's rated current ranges from 0.15 A to 0.9 A, offering a balance between power consumption and torque output. The mass of this motor can be anywhere from 0.65 kg to 7.5 kg depending on the specific configuration. In industrial settings requiring reliable and accurate stepping, this model provides consistent performance. It withstands voltages up to 1 KV AC which is a key feature for safety and reliability.

Featuring a clockwise output shaft rotation with internal wiring set to CW, this motor ensures consistent movement in its designed application. The ambient temperature range of –10C to +50C allows for deployment in a variety of harsh environments and this makes it suitable for many different industrial setups, especially the ones that undergo constant temperature change. As a versatile option for industrial automation, this model integrates well into varied applications and uses. The device's design ensures it can function effectively in environments with humidity ranging from 20% to 95% RH (no condensation), important for long-term reliability through diverse operating conditions.

This motor operates at approximately 72 rpm at 60 Hz and 60 rpm at 50 Hz, providing stable output speeds and it delivers consistent performance under various conditions. The lead wiring complies with UL3266, typically using AWG22 gauge wire, ensuring a safe and robust connection. A maximum temperature rise is specified up to approximately 80 K based on standard testing protocols, proving the motor's capability to maintain steady operation without overheating, a very specific but important test. The motor's design, including the output shaft rotating clockwise, suits applications through which controlled, consistent movement is essential for operational accuracy.
