Precision Microdrives has increased the vibration output of its 310-101 10mm coin vibrator motor, which is suitable for handheld applications such as mobile phones.

The 310-101 vibrating motor features a compact size, a straightforward self-adhesive mounting method and an enclosed, shaftless design.

The newly updated 310-101 is claimed to offer a very high vibration output amplitude.

It remains a 10mm shaftless vibrating motor with a brushed commutation mechanism, and its typical output has been increased to 1.2g (11.72m/s).

A brushless 10mm motor, known as the 310-109, is also in production.

The brushed commutator offers a standard runtime (before a 30 per cent change in performance) of 100,000 cycles (one second on, one second off), whereas the brushless version is rated at 700,000 cycles (seven times longer).

According to the company, using vibrating motors in handheld devices is an excellent way to signal alarms and other events to users and operators.

A vibration alarm mechanism is non-intrusive and is localised solely to the operator.

This is useful for tools that are utilised in environments where there is a lot of noise and where visual indicators such as displays and lamps might be hard to see.

The 310-101 motor measures 10mm in diameter, has a height of 3.4mm and weighs in at 1.2g.

Like all shaftless coin motors, the nominal voltage rating is 3V, and there is a 2.3V start voltage that the user must observe to ensure the motor will start in every orientation.

When running at 3V, the motor produces a vibration frequency of 11,000rev/min (183Hz) and an increased amplitude of 1.2g (11.72m/s) of vibration under the Pico Haptic range inertial test load of 100g.

The current draw is typically around 65mA and the motor efficiency is rated at 6.3g/W.

Audible noise is typically less than 40dBA, and the motors have an operating temperature of -20C to +65C, which can be extended by request.

The motor comes as standard with AWG 32 flying leads, which can be modified in several ways upon request.

The motor can be mounted in a recess in the product enclosure or simply stuck to a flat surface or printed circuit board (PCB) via its self-adhesive pad.

This is based on long-life 3M high-strength adhesive tape.

The company’s Pico Haptic range of micro vibration and pager motors is built around designers’ requirements for vibrating motors that can be used in a variety of implementations.

The range contains PCB-mounted vibration motors, leaded vibration motors with customisable connection options and a variety of mounting and encapsulation options.

Precision Microdrives

Precision Microdrives is a reliable and competent UK-based supplier of precision DC electric motors. We manufacture precise, miniature, low-voltage, DC vibrating motors, DC reduction gear motors, and DC brushed motors. We stand for delivering our motors on time and to spec.

We carry a wide range of stock DC vibration motors, gear motors and brushed motors with frame sizes from Ø4mm ~ Ø100mm and offer next-day delivery through Europe. We also manufacture customised and high-volume motor requirements to specification.

Most customers develop customised motors from our base (stocked) range of parts. Common changes include performance alterations, and the addition of wires, looms, connectors and output mechanisms.

Our motors are used worldwide in automotive, medical, consumer, handheld and instrumentation applications. We lead the market in tactile vibration (haptic) feedback and vibration-based operator alerting, and make many of the smallest DC geared motors commercially available.

We have a helpful application and engineering support team, which offers free advice on how to integrate our parts into designs. It also designs and manufactures complete products where precision motion forms the core of the design; our specialisation, is in high-end consumer and medical products.
