PM20L-020-CTD3

The PM20L-020-CTD3 is a small PM (permanent-magnet, can-stack) stepper motor about 20 mm in diameter. The 020 in the part number means 20 full steps per revolution, so each step is 18°. It sits between the miniature 15 mm and the 25 mm PM motors in size, and suits compact devices such as gauges, small locks, valves and hobby mechanisms that need controlled, repeatable rotation.

PM20L-020-CTD3 Specifications

• Motor type: 2-phase permanent-magnet (PM) stepper motor
• Body diameter: about 20 mm (from the PM20 code)
• Full steps per revolution: 20
• Step angle: 18° full step, 9° in half-step mode
• Variant code: CTD3

PM20L-020-CTD3 Applications

• Gauges, dials and indicator needles
• Small locks, latches and valve actuators
• Compact robotics and animatronics
• Arduino and ESP32 learning projects

What's in the Box

• 1 × PM20L-020-CTD3 stepper motor

Tip: Small PM steppers run best at low step rates; begin around 100 steps per second and adjust. Use a low-voltage H-bridge driver such as the DRV8833 or L293D and check the motor's rated voltage before connecting a supply.
