High Frequency / Precision Drives by Design

​

SPINDEL Master is a line of universal high frequency drives, suited for operation of a wide range of 3 phase AC motors, from standard “low speed” motors rated 50 or 60 Hz to high speed motors rated up to 3200 Hz (over    190 000 RPM for 2 pole design).

 

SPINDEL Master drives are differentiated from “standard” AC drives by the special attention which is given to specific needs of high frequency (low inductance) motors. The design was optimized around quality of voltage and current waveforms at any speed, low drive induced motor losses and vibration (bearing temperature and life) and control features which high speed motor applications typically require.

High Quality Output for High Speed Motors

​

Synchronized high frequency PWM control method significantly reduces harmful harmonics in motor current, compared to most PWM type high frequency drives. Standard included output filter additionally improves motor losses (heat), vibration, and voltage peaks which result in longer bearing and stator winding life. 

 

Synchronized high frequency PWM control method combined with high PWM carrier frequency significantly reduces motor losses (heat) and vibration, resulting in longer bearing and stator winding life. This approach results in better performance compared to most PWM type high frequency drives. Output filter is included as standard which further improves motor current and voltage wave forms.

​

Advanced Motor Protection

​

All three phase motor currents are continuously monitored by dedicated fast circuits for safe and expected values, for phase current differences (phase imbalance), for open connection in one phase and for short circuits. If the insulation in a motor phase fails, SPINDEL Master drives will indicate which phase has a problem, which greatly facilitates troubleshooting.

 

Load sensing measures real motor load and is fast and precise. Programmable timed-overload function permits transient overloads while thermally protecting the motor. A circuit is included for monitoring of stator winding temperature via PTC thermistor style sensor.
