NSK Espert 500 – Electric Micromotor – 50,000 rpm

Description

The NSK Espert is hands down, the best Electric Micromotor system we have ever tested.

The ESPERT 500 Brushless Motor takes motor technology to an even higher level. This new state of the art motor has dramatically increased efficiency and torque output. The microprocessor based control unit provides optimal control of the motors and allows for increased flexibility in this multi-function system.

• Realizes high output power of up to 200W and high durability through the combination of a high-performance brushless DC motor and high grade electronics
• High power system: max. output 140W
• Speed range: 1,000-50,000 min^-1(rpm)
• Microprocessor controlled for optimal motor control
• Hand switch [NAKANISHI Smart Switch]
• Memory speed function [FiXpeed]

The brushless motor and incorporated cooling fan have reduced the vibration and noise levels, resulting in a quieter, more comfortable work environment. Dramatically compared with conventional grinders. High performance brushless motor eliminates the need to change carbon brushes. NAKANISHI’s internal load test has proven continuous use for more than 5,000 hours.

NAKANISHI’s ultra-precision technology ensures bur concentricity of 0.02 mm (0.0008″) or less,which allows for very high precision finishing.

Speed is variable from 1,000~50,000 min-1 (rpm). Smooth and powerful torque is delivered at both high and low speeds. The extremely high maximum speed of 50,000 min-1(rpm) allows high precision micro-machining.

The switch provides a click sensation and a confirmation tone is produced by the controller when the switch is operated. The motor type is distinguishable by the switch color.

The handpiece has a patented built-in-dust protection system to prevent the infiltration of dust and debris into the front bearings. This NAKANISHI patented design assures long-term durability.

The operation of all Espert 500 functions is controlled by a high performance microcomputer (CPU) that is programmed with NAKANISHI’s proprietary technology. NAKANISHI’s CPU has direct control of the brushless micro-grinder allowing smooth and highly precise cutting and polishing of a wide variety of materials. Bur “chatter” has been eliminated. The system automatically senses which micromotor is attached and self adjusts to provide optimum micro-grinder performance.

If you’re serious about wood carving, there is not better choice than the NSK Espert 500. It has the most torque and highest speed of any of our electric engraving systems.
