1027 3V Flat Mobile Phone Vibration Motor

1027 3V Flat Mobile Phone Vibration Motor (DC Pager Motor) is an ultra-compact, brush-type DC motor designed specifically for generating tactile feedback in small, portable devices. This coin-style motor, utilizing an Eccentric Rotating Mass (ERM) mechanism, effectively converts electrical energy into a powerful vibrational force within an extremely thin profile. Consequently, design engineers widely select the 1027 motor when space is at an absolute premium, such as in wearable devices and compact electronics. The low nominal 3V operation makes it an ideal fit for direct connection to lithium battery supplies or standard low-voltage logic circuits. Therefore, you can easily integrate this motor to add crucial haptic feedback functionality to your next space-constrained project.

Key Features:

• Flat Coin Design: The extremely low profile (i.e., 2.7 mm thickness) allows this motor to fit seamlessly into thin casings and small circuit boards.
• Eccentric Rotating Mass (ERM): This mechanism produces strong, discernible vibrations despite the small footprint, ensuring effective haptic alerts.
• Low Voltage Operation: It operates efficiently at 3V DC, making it highly compatible with battery-powered mobile and wearable applications.
• Brush Motor Type: Provides reliable start-up and a high rotational speed for quick vibration response times.
• Solder Pad Connection: Features two contact points/pads on the body for secure and easy soldering into flexible PCBs or tight enclosures.

Pinout and Wiring:

• Wiring Note: This is a DC motor, therefore the direction of rotation does not affect the vibration. Connect the positive supply (V_CC, e.g., 3V) to one terminal pad and Ground (GND) to the other terminal pad.
• Control Circuitry: Always drive this motor using a low-side MOSFET or a transistor (like a BJT) and a flyback diode to protect the control circuit from inductive kickback.
• Polarity: Although not strictly critical for vibration function, observe polarity during initial setup for consistent electrical testing.
