Festo EMMT Series Hybrid Stepper Motor 48V, 0.25Nm Torque, 1.8 °, 42 mm Frame, 5 mm Shaft

This stepper motor converts electrical pulses into precise rotary motion for positioning and speed control in automation and motion systems. It operates from a 48V supply and delivers consistent step increments at an output speed up to 600rpm. The 5mm shaft and panel-mount configuration suit installations requiring Compact drive elements with accessible mechanical coupling. The unit meets recognised safety and material restrictions to align with regulated equipment environments.

• 1.8° step angle provides fine positional resolution
• 0.25 Nm holding torque maintains static loads without drift
• 1.8A current rating supports moderate driving power
• 2.1 Ω resistance per phase enables predictable thermal behaviour
• 50 pole pairs enhance torque density for slow-speed tasks

• Suitable for CNC robotics requiring precise motion control
• Ideal for laboratory automation with moderate load requirements
• Used with rotary encoders for closed-loop microstepping systems
• Can be used for pick-and-place mechanisms in production lines

The drive shaft is 5mm in diameter with a 24mm projection for secure coupling and common connector interfaces.

The rating is IP40 which protects against solid objects larger than 1mm but offers no water resistance, so indoor dry installations are recommended.

The motor requires a 48V supply and a rated phase current of 1.8A with 2.1 Ω per phase resistance for correct torque and thermal performance.

Having 50 pole pairs increases electromagnetic interaction per revolution, improving torque at low rotational speeds and smoother microstepping response.
