EM700M series spindle servo drive
Product Introduction
The EM700 series permanent magnet synchronous motor drivers utilize the 
industry's leading sensorless vector control algorithm, enabling permanent 
magnet synchronous motors to achieve optimal performance under open-loop 
control. They are widely used in industries such as new energy vehicles, air 
compressors, high-speed magnetic levitation fans, ceramic ball mills, and mining 
machinery.
Function Introduction:
1. Power range: 0.75KW~500KW.
2. Use speed sensorless (open loop) vector control.
3. High starting torque, open loop vector control can output 150% rated 
torque at 0.5Hz;
4. PG card: Differential encoder PG card, resolver PG card and open collector 
encoder PG card are optional.
5. Automatic Voltage Regulator (AVR): Maintains constant output voltage when 
grid voltage fluctuates.
6. Superior Braking Performance: When rapid stopping is required, a suitable 
brake resistor enables rapid stopping.
7. Protective Features: Due to the high levels of metal dust and oil 
contamination found in lathes and other environments, the driver incorporates 
special protective measures specifically designed for these challenging 
environments to ensure normal operation.
8. Parameter backup and restore: After the user sets the parameters, they can 
be backed up and restored with one click .
Applications:
New energy vehicles, air compressors, high-speed magnetic levitation fans, 
airports and other applications.
