ERM motor

NOTE: Our versions have a blue housing, not black like in the picture.

Our Z4TH5B1462252 is designed for application where low power consumption is the primary design consideration. The price point of this motor is much higher than our standard vibration motors making it impractical for toys and other low cost consumer applications. The motor is surrounded by a rubber boot that allows it to be press fit into the desired location in your devices housing.

This motor is similar to other Z4TL series motors, but it our uses a smaller counter weight. The silicone rubber boot running the length of the motor allows the motor to be press fit into a cavity in your products housing. You may request that this rubber boot be added to any of our Z4TL family of vibration motors.

Body Diameter 4.4 mm

The Z6CL2A0540722 water resistant motor vibration motor is ideal for imbedding into an object or in any environment where there is a possibility that something might impede the free movement of the counter weight.

ERM Motor

The DRV2605 from TI is a fancy little motor driver. Rather than controlling a stepper motor or DC motor, its designed specifically for controlling haptic motors - buzzers and vibration motors. Normally one would just turn those kinds of motors on and off, but this driver has the ability to have various effects when driving a vibe motor. For example, ramping the vibration level up and down, 'click' effects, different buzzer levels, or even having the vibration follow a musical/audio input.

This chip is controlled over I2C - after initialization, a 'string' of multiple effects can be strung together in the chips memory and then triggered to actuate in a row. The built in effects are much much nicer than just 'on' and 'off' and will make your haptic project way nicer feeling.

According to the product page, it can be used with both LRA (Linear Resonance Actuator) and ERM (Eccentric Rotating Mass) type motors but we have only used it with our little vibration pancake ERM.

We put this nice chip onto a breakout board. it works with both 3V and 5V power/logic, we have code specifically for Arduino but porting it to any I2C-capable processor should be quite simple. Check it out and get buzzing!
