Product Description:
The 4VM82-220-6 is a servo motor manufactured by Pacific Scientific. It is part of the Low Inertia PMDC Servo Motors series. It is one of the highly in-demand products in industrial automation sector.
The 4VM82-220-6 servo motor rotor inertia is 0.00074 oz-in-sec². It comes with a tachometer that has a voltage ripple of 1.5% peak-to-peak (max) which provides smoother and more stable feedback for closed-loop control. The motor optimal operating voltage is 30 volts in which it performs as designed. It has a robust, cylindrical industrial housing and signifies durability and reliability in industrial environments. The root mean square current the motor draws under normal operating conditions is 7 Amps which gives an idea of the power supply requirements and heat dissipation considerations. The amount of torque it generates per ampere of current is 8.9 oz-in which suggests relatively strong torque performance for a servo motor of this size. Its design supports easy coupling to mechanical loads and allows secure and aligned installation into machinery. You can get this PMDC servo motor with a one year warranty by Wake Industrial.
The 4VM82-220-6 motor resistance in the tachometer windings is 50 Ohms which help reduce current draw and is typical for signal-level outputs. The main motor winding resistance is 0.89 Ohms which indicates high current capability and lower resistive losses that makes the motor more efficient. Its tachometer outputs 2.5 volts for every 1000 RPM of shaft speed which is used for velocity feedback in closed-loop control and gives precise speed measurements. It is designed for efficient cable management and protection and its angled feature helps in space-restricted installations and minimizes wire stress or strain.
