Aerotech's latest BMS range of brushless servo motors use a novel slotless stator design to unsurpassed velocity control with zero cogging.
Aerotech's latest BMS range of brushless servo motors use a novel slotless stator design to unsurpassed velocity control with zero cogging.
Described by the company as the ultimate high performance rotary motors, the new BMS motors have rare earth neodymium iron boron magnets and a high pole count rotor to deliver maximum torque and acceleration in a small package.
The motors are ideal replacements for AC or DC, brushed and brushless motors in metrology, machine tool or scanning applications and elsewhere where superior velocity smoothness and control are required.
Better stability and easier tuning are a result of the motor's ability to match more closely the inertia of mechanical systems.
It does this thanks to the slotless stator which, by the nature of its construction, inherently eliminates cogging and results in the smooth velocity control.
A variety of encoder options can be fitted to the motor to suit specific applications.
In addition to the standard RS422 line driver output, an optional sine wave encoder can be used to provide ultra-high resolution.
Indeed, Aerotech's own MX multiplier box accepts sine wave encoder and RS422 line driver outputs to enable resolutions over 4 million counts per motor revolution.
Two sizes of BMS motor are immediately available in 175W and 217W with rated speeds of 4000rev/min and 3000rev/min and constant torque ratings of 0.16Nm and 0.32Nm respectively.
Maximum acceleration is 85,000rad/sec2 and 74,000rad/sec2.
Like all brushless motors, the BMS range is more reliable than DC brushed equivalents.
