<p>The linear drive motor is based around a proportional solenoid L1, to which is connected a velocity transducer F1. The velocity output of the transducer F1 is compared to a reference voltage V1 by an error amplifier/driver A1, which in turn drives the solenoid L1. This gives velocity control to the linear motor, without the usual disadvantageous rotary to linear conversion mechanisms. The linear motor therefore has a higher bandwidth, and is free from mechanical vibrations and resonances, and from backlash.</p> |
