<p>A method of actuator coil temperature control for actuators that are not continuously operated, wherein when an actuation current is not being applied to the actuator coil, a) sensing a parameter indicative of the resistance of the actuator coil as an indication of the temperature of the actuator coil, b) if the sensed parameter indicates the temperature of the actuator coil is below a first predetermined limit, then initiating a series of successive actuation current pulses to the actuator coil, each actuation current pulse being terminated before actuation of the actuator occurs, and c) periodically repeating a) and b).</p> |
