Micro motor offers a small footprint

SANYO DC Micro Motor Division has developed a vibrating micro motor featuring a low profile of just 3.4mm, in a SMD package.

Sanyo DC Micro Motor Division has developed a vibrating micro motor featuring a profile of just 3.4mm in an SMD package.

The new Sanyo BSY series DC motor is ideal for applications requiring a small foot-print on surface mount circuit boards.

The new series is available in an 11mm length.

Applications for this new micro motor include mobile phones, consumer medical devices and other small hand held devices, in OEM quantities.

Also targeted are medical and other applications requiring disposable functionality made possible due to the low unit cost of the motors.

The series is suitable for devices weighing 80g or less.

The BSY series was originally designed for the latest feature rich but compact mobile phones to alert in-coming calls silently.

"The surface mount configuration provides a compact and extremely reliable solution, without the possibility of contact failures seen in spring loaded designs", explains Shane Snipe, Manager and Mechanical Engineer for Sanyo's DC Micro Motor Division.

The motor measures 11mm long, with body 4.4mm wide x 3.4mm high off the mounting surface.

Typical speed is 14,000rev/min with a counterweight of 1.7mm radius and 2.8mm length.

Mechanical noise is 45dB max.

Electrical noise is controlled by a ring varistor.

Standard operating voltage is 2.7V DC.

Load current is approximately 65mA.

Operating temperature range is -20C to +70C.

Storage temperature range is -30C to +85C.
