SANTA CLARITA, Calif. – H2W Technologies Inc. in Santa Clarita, Calif., is introducing the LCAM 5/15 DC linear brush-type servo amplifier for high precision power electronics and motion control in semiconductor, medical, and optical equipment.
Linear amplifiers enable the power current to flow continuously to the motor, which prevents any dead-band issues that occur in many Pulse width modulation (PWM) amplifiers.
Additionally, linear amplifiers have low electromagnetic interference (EMI), and no audible noise that also can be found in many PWM type amplifiers. Therefore because of their high current loop bandwidth, coupled with a low EMI, this leads to a smooth motion profile.
The DC linear brush-type servo amplifier often is used in precision stages to drive linear motors or voice coil actuators in semiconductor, medical, and optical equipment, since most voice coil actuators have very low inductance windings (less than 1 millihenries), this makes a linear servo amplifier the preferred method to drive voice coils.
